Re: Error: You established and aborted connections too frequently?

I have to agree - we regularly get connections dropping in China and I have team members regularly get locked out because of trying to connect on a poor quality connection.

I wish we had not pushed TeamViewer to our colleagues abroad in years gone by, as we're now stuck with third parties who expect us to use it.

Very dissapointing reply from TeamViewer.

Re: Error: You established and aborted connections too frequently?

Are you serious right now?  That's the answer? 

CLEARLY, Team Viewer was created and desgined by team members who are no longer existent within your company.

You guys are unable to update and change the code, I'm willing to believe that.

If you'd like some consultation on proper DR Testing, Dev, QA, ...any ITIL needs at all... reach out to me.

Your answer solidified my desire to NOT use this software anywhere currently...

Didn't realize you were still in Beta as it's clearly not Production-Ready.   You should probably warn users of that before roping them in.

Who are you trying to fool?
This "brute force protection" is counting connection attempts that never even got to the password exchange phase and connection attempts to computers that are assigned to us with easy access.

Re: Error: You established and aborted connections too frequently?

I recently engaged with my salesperson who wanted to sell me on the latest version (currently using v.12). I politely told her that I wasn't interested in buying anything until they listened to their customers about this very issue.

Her response:
"Thank you for the reply and feedback.

I do see the posting was initially submitted on 04/06/2017 and we addressed it the same day. The response is below:

This is actually an important security feature in TeamViewer, which has existed for quite a long time. The feature exists as one of the methods we use to protect TeamViewer from brute-force attacks from botnets or would-be hackers.

If someone tries to make multiple connections to the same TeamViewer ID over a short period of time, they will automatically be blocked, for several minutes, from making further connections. This will happen if you click the "Connect to partner" button repeatedly.

You will need to wait for the indicated amount of time before being able to connect again.

I did speak with high level support and they suggested I create a ticket for you in order to determine if a weak internet connection or something else is causing this. You will get an email with the ticket # which will request the logs from both of sides of the connection. If you can reply with these logs are support team will be able to tell you exactly what is going on. As a customer you qualify for live support vs. the free version community.

I hope you are able to get this resolved with support and please do reach out to me regarding any licensing concerns."

Their support team did reach out to me, but wanted me to install something else on my computer that collects information and refused to provided ANY information about the data it collects.

My continued annoyance is due to them thinking that their one response (which was rubbish, and didn't provide any more details than we already knew) qualifies them of "answering the question."

This and the latest issue about them not being clear to their paying customers regarding downtime is really leaving a bad taste in my mouth.

Believe me, I am looking for other solutions. Changing is painful, but I am trying to determine which is more painful, long-term.

Re: Error: You established and aborted connections too frequently?

Brute force protection is not only there to protect the remote side.

Even if you try to establish too many connections quickly to multiple different devices, this is still covered by brute force as there are too many requests being sent to the server that can be used to overload our servers, this is why there is no "Override" button.

Also, please read up the thread. One of our supporters, Jeremy has replied multiple times to this thread with the same answer. I am definitely not the first staff member here.

Making sure that the server is not overloaded or attacked is clearly to our customers advantage.

I'm not sure how you could argue that making sure the service works is purely to our advantage and not to our customers.

Re: Error: You established and aborted connections too frequently?

So a few thoughts:

You need to actually tell YOUR CUSTOMER "Please wait 10 seconds before reconnecting..."

That would've probably stopped this entire thread right here.

Secondly... do you think a hacker is going to manually "click connect" on a button a million times in order to flood a network?

Is the human finger that fast anyway?

Even an autoclicker, would fail, if you had that warning about 10 seconds.

If there IS A DDOS somehow via the frontend... thats a vulnerability in the software you're not telling us about that you can't figure out how to fix.

Which raises 197 more questions.... do we need to uninstall now?

Re: Error: You established and aborted connections too frequently?

Scotty:

"Brute force" is a term that refers to password cracking, not denial of service attacks. Are you saying that a human manually tapping the refresh button 10 times in 10 seconds is enough traffic to be classified as a denial of service attack by the teamviewer network? That requires a lot more explanation before it will be plausible.

But if we assume that's true, that implies the teamviewer network is way too small to meet its demands due to being underfunded or poorly architected.

But let's assume that this network problem is actually intrinsic to all remote desktop systems rather than just teamviewer and any higher performance on other services is a result of them temporarily operating at a loss in order to try to compete with teamviewer. In that case, the development team should take a long hard look at the use cases "flaky or intermittent connection", "old or overburdened pc", and "intermittent pc uptime". It should be designed so people can connect and stay connected in these cases without having to manually poke the button until they get connected or banned.

Or they can just keep telling their PR people to spin it as a good thing.

Re: Error: You established and aborted connections too frequently?

I have  to chime in and agree here. There are enough bugs and holes to jump through when setting up TeamViewer--multiple aborted logins are kind of par for the course. This timeout/security parameter should be left up to the user to adjust in Preferences; or there should be some quick way to override, like e-mail validation or 2-factor authentication.

I can't complain too much since I'm using the free license just for my home, but this happening to someone with a paid license during an important meeting would be a disaster. It really is something you folks should consider changing if you haven't already.

Re: Error: You established and aborted connections too frequently?

Hi Scotty.

 

I am sorry but you (when I say "you" I mean the whole TV support who have answered to this thread) keep running away from the main point brought up here by most of the users.

I believe most people who have commented here will agree that WE UNDERSTAND the security need of this feature, HOWEVER, you cannot apply something like that WITHOUT warnings to the user. In ANY kind of system there will always be some kind of warning or notice that failure attemps will have a cost, and this cost NEEDS TO BE INFORMED.

If you could at least:

1) Warn the user BEFORE IT HAPPENS that after "x" attemps it will get locked out; and/or

2) Inform the user HOW LONG WILL TAKE to get the connection restored

If you would only apply those two things I am 100% sure that this thread (and others similar to it from my Google search about the issue) would be reduced drastically and less worry for you too. LET THE USER KNOW HOW IT WORKS in as much advance as possible, that's really simple.

I am not even going into the details of DoS technical details (as I agree with other users that this has nothing to do really with DoS attacks), just implement that and I believe most people will be happy.

I have a 12v paid license, and have been unable to help a staff of the company I am System Admin at because of that.

PLEASE LISTEN TO YOU CUSTOMERS, that's all.

Regards.

Re: Error: You established and aborted connections too frequently?

Scotty and other admin - your attitude towards paying customers that are complaining about a feature that is clearly broken ( you guys state 10 minutes - some of us have to wait hours) isn't going un noticed. We are an MSP, have hundreds of remote agents and are now moving away from TeamViewer. Great going and we are going to make sure we let all of our other MSP's we deal with what garbage and **bleep** service you guys provide,

We had 3 remote nodes that have DEDICATED agents installed start doing this today. Client had an ISP issue which we were assisting remotely and since the connection dropped every few minutes we got "flagged" by this POS software and now cannot log in. Had to sign up for another service for remote support and since TV made us do that we are moving ALL of our clients to new solution.

This limit just hit me when connecting to a flaky machine, I've disconnected and reconnected about a dozen times in the last two minutes and now it's telling me I have to sit and wait.

Brute force protection is a good thing, but valid correctly-authenticating connections are not a brute force.


I want to second this. I have a linux web server that I check every morning and every morning I need to attempt to connect to it between 3 to 6 times for TeamViewer on this server to "wake up" and start accepting logon requests. Sometimes it doesn't wake up and I exceed the number of times I can connect.

Re: Error: You established and aborted connections too frequently?

I agree that you need security but I now sit waiting for "some time" which may be 15 min just because my connection dropped and I pressed retry too often. SO.. 

 

I fully agree with implementing security, BUT let me access the management console and remove the lock in 1-2 min rather than wasting 15 min of my time and more importantly wasting 15 min of my customers time - I'm just losing money/time/patience, my customers are losing faith in me fixing the issues they have and thats far far worse. 

I also note that any progreammer with a small brain could implement a try 4 times then sleep 15 min then try again process - this is not the right fix but thats another thing... 

so in summary yes please do keep me and you secure but let me have some control rather than using the brute force method of a timeout.

Absolutely. When you've got a customer on the other line and you tell them to "wait a while", you can imagine what sort of reaction you will get.

Hi there, 

Thank you for your messages.

I recommend you to restart the TeamViewer service on your Windows devices.

-Execute "run", type "services.msc" and press OK

-Now find TeamViewer, and restart it by doing a right click.

Then, restart the TeamViewer application - the best would be to restart it on both sides. It should work again.

I hope this could help. If not, do not hesitate to contact us again.

All the best,

Re: Error: You established and aborted connections too frequently?

@Natascha 

How are we supposed to restart the service on a remote computer when we can't connect to it?  If we have configured the TV application properly on the end-user's machine, then the end-user will not be able to restart this service because they lack elevated privileges.  And even if they had the proper privileges to restart the service, this is an ineffective bandage at the most.  The end-users’ machine could be rebooted, which would essentially restart the TV service, but this has proven to be ineffective in several instances.

What we are all saying in this thread is that the suggestions of TV staff in the past simply do not work.  The messages TV gives us are vague and leaves us in the dark when we are trying to give our clients an estimate of when we can help them.  This is a huge embarrassment when we are trying to support an and-user and we are clueless as to what is preventing us from connecting to their supported workstation.  The lack of any useful detail makes us look like we don’t know what we are doing.

This is a real problem; not just a picky complaint.  I hope, out of respect for all paying TV customers, you have read all the other comments in this thread before posting.  Many agree in this thread that TV staff are not facing this issue directly, and ultimately this lack of response will drive many of your paying customers to use another solution.  I imagine there are many others who are having this problem, but simply do not waste their time to post on this thread.

Your response is adding to the continued lack of attention from the TV staff.  It seems that TV staff in general are either (1) not able to actually fix this problem and won’t admit it, or (2) refuse to spend any time in fixing it.  I am dumbfounded that after all the people that have weighed in on this issue, TV staff continues to ignore this problem.

Hi @cirEOak 

Thanks for the detailed post. 

I clearly read all the comments before, because I need to know what I'm talking about before I post an answer. The Brute Force Protection is really necessary to protect our users from Brute Force attacks. 

Therefore, we exponentially increase the latency between connection attempts. 

Can you at least try to restart the service on your side? I'm aware, that not every user on the remote side has enough permissions to restart services or exit TeamViewer at all. 

Please make sure to use the right passwords before you try to connect.

Have a nice day,
Natascha

Re: Error: You established and aborted connections too frequently?

@Natascha 

Why are you all so defensive?  It's like no TV staff can get past trying to defend the product.  There are some obvious flaws regarding the lack of helpful details in error messages.  The actual issue itself is one thing, but details about the issue (especially how long we are locked out) are just as important.

To answer your question, of course I have tried to restart the TV service on our end.  For this issue, I have rebooted over and over and have even had the end-user reboot their machine over and over, to no avail.  The HUGE issue is lack of details from the TV error message.  We have no idea how to troubleshoot.  Is it a DNS issue?  Is it a service issue?  Is it an IP issue?  We don't know because all we get is, "You established and aborted connections too frequently.", when we were simply trying to connect to a supported client that is part of our supported computers, listed in our TV inventory, with a local password set.  The correct password was used.

But here we go again.  We (the paying customer) mention something, and TV responds with more unhelpful information.  If there is more response from TV, then please make it helpful!  Stop being so dang defensive because it appears that TV has a stronger effort to focus on defending it's product rather than understanding what we are facing.

I am unsubscribing from this thread because since 2017, there has been nothing useful to help us find some resolution to this issue.  These unfriendly and unhelpful responses from TV have caused me and several others a ton of stress.  Most other products that I pay for have a support staff that actually listens to their customers and provides solutions.  I can't say that I have received that from TV.

Re: Error: You established and aborted connections too frequently?

I've been a paid subscriber a little over a year and this is the first time I've run into this issue because I was trying to connect to a customer with a bad internet connection. I understand the reason it happened, what I don't understand is there's no specified time that I have to wait, which is frustrating because my customer and I have to just sit and hope it's 10 or 15 minutes.

Maybe there should be a message on the host side that would alert the customer there have been several failed attempts so they can reset the lockout and allow the connection instantly.

Re: Error: You established and aborted connections too frequently?

I have just been hit by the same lockout while trying to help a family member.
Their router needed rebooting so I just kept on trying to connect, not realising that I would get locked out for my sins.

I have read the whole thread and I too am astonished by the lack of understanding by TV staff. We all realise the need to avoid Brute Force or DDoS attacks, but trying to use the TV client to connect to a non-responsive host can hardly be classed as either. I made 10 attempts over a period of 5 minutes - checking the log they were all logged as:

CCreateClassicSession::HandleRequestRouteResponse(): Response: NOROUTE_LoggedOut@RouterIp

Then of course it became:

CCreateClassicSession::HandleRequestRouteResponse(): Response: NOROUTE_ExcessiveUse@RouterIp=

May I remind you that your "hacking" protection was triggered by trying to connect to an unresponsive (off-line) host, no passwords were involved. Perhaps you could review your code so that initial connection failures do not count as Brute Force attacks?

Re: Error: You established and aborted connections too frequently?

Thanks for your link to the brute force protection page. But this is not what is happening. 

"It thus takes as many as 17 hours for 24 attempts. The latency is only reset after successfully entering the correct password." 

We, as support representatives are 100% using correct passwords (usually in my case by way of having a saved computers list for sites we look after, and passwords for sites set by group policy etc) this happens after multiple SUCCESSFUL attempts to connect off the back of flaky connections. 

This has been reported for over 2 years and there have been no improvements. Including no reply to the guy who was blocked from connecting to his own machine for 6 weeks as a result of this poorly thought out, poorly executed strategy. 

Also someone at TV needs to look up what brute force means, likewise DoS. Trying to support your customers is not that. Trying to reconnect over a flaky connection is not that. Trying to connect, for example 5000 times a second to multiple hosts with sequential password hashes is.

Re: Error: You established and aborted connections too frequently?

Hmmmm?!?

I have NOT actually "established and aborted connections too frequently"

I have not aborted anything. TeamViewer has done all the aborting.

The "Connect" button is visible, and the green dot and "Ready to connect (secure connection)" shows in the lower tray.

I click the "Connect" button.

The button changes to "Abort", and the yellow dot and "Connecting to partner" shows in the lower tray.

Within less than a second, TeamViewer changes the button and the tray back to the "Connect" state.

I never aborted anything.

My "local" machine is Windows 10 Pro, and my "remote" machine is Debian 10 Buster.

On both machines, TeamViewer is automatically started upon reboot, and both have personal passwords assigned.

Oh, and did I mention that my "local" machine is on my desk, and my "remote" machine is on the reference table immediately behind me?

My local machine is connected to my router via wireless, but my remote machine is hardwired to the router via ethernet. Ping works very well, thank you.

I have rebooted both machines, thus restarting TeamViewer on both. The problem persists. The problem is NOT a "wrong" password - TeamViewer never gives me a chance to enter a password.

I have been trying out Teamviewer for a few weeks now, but only recently has the inability to get to the password entry box become a problem. It has gotten worse and worse for a couple of days, and is only now today giving me the dreaded "Error: You established and aborted connections too frequently" message.

I have read this entire thread and have seen that this problem has persisted in the community for two years now.

Unless this matter somehow gets addressed and properly corrected in the very near future, I'm afraid I will be unable to recomment TeamViewer...

To anybody...

Ever!
