Ubuntu Linux refuses to connect to Teamviewer servers

Hello, I am using Ubuntu Server 16.04 and I have reinstalled and started from sratch about 12 times in an attempt to get Teamviewer working. Each time it refuses to connect to the internet asking me to input proxy settings but no matter what I input it refuses to connect.

I am using LXDE as my desktop environment and it works under xrdp but not teamviewer.

I have tried this with both Teamviewer 11 and Teamviewer 12 and both give the same issue.

That worked for me

Thank

NEOlit

maybe that's just a crutch, but i've just edited my hosts file and it worked.
just add a string into it under numbers to make it look:

127.0.0.1 localhost
127.0.0.1 (your_device_name) - do not add this 2 strings, it already should be there. just add one below
54.230.228.12 linux.teamviewer.com

I have the same problem with Ubuntu 17.10

@johnnycatt: That did the trick for me. No other solution above worked. Its really frustrating.

Also the Sign in button behaves like it doesnt work which also was solved after purging and reinstalling

OS: Debian 8.10

Having the same issue. Unfortunately, Mark's plan didn't work for me...

I don't shutdown my computer often, so I can tolerate this problem for a while. My "workaround" is to "sudo apt-get purge teamviewer" after every reboot, then reinstall my copy of Teamviewer12 -- it works flawlessly!

It only takes a minute, but it's aggravating… and if there was a power failure on the other end, I cannot connect to that Ubuntu computer either...

No, I don't think so.

And for another method that does seem to tinker somewhat poorly sadly, is to install "Unbound".

I like this method because many people think Ubuntu's "resolved" is garbage and often causes the exact problem that teamviewer has in Ubuntu.

So here is my relatively simple way, it can seem overwhelming to config on so many other posts.

the latest Ubuntu's DNS problem with DNS and systemd-resolved that solved the issue for me

The steps are :

1/ add a line nameserver 8.8.8.8 in /etc/resolv.conf

- - - - sudo nano /etc/resolve.conf
  - 2/ install unbound with sudo apt-get install unbound
  - 3/ disable the troublesome daemon with:
    - - sudo systemctl disable systemd-resolved
        sudo systemctl stop systemd-resolved
  - 4/ add dns=unbound in the [main] section of /etc/NetworkManager/NetworkManager.conf
    - - sudo nano /etc/NetworkManager/NetworkManager.conf
  - 5/ enable unbound with:
    - - sudo systemctl enable unbound-resolvconf
        sudo systemctl enable unbound
      - Reboot the computer
I hope this helps, Mark

OK, So here is a BETTER FIX Revisited that survives reboots! And I may have to apologize to Reyhan (TeamViewer Moderator) as it MAY be just an Ubuntu problem. (I say MAY because I still think TeamViewer must be able to find a solution if they REALLY CARED 1 1/2 years LATER!)

But here it is - and Easy-Peasy too.

1st Edit a file called, "/etc/systemd/resolved.conf"

sudo nano /etc/systemd/resolved.conf

Find

#DNSSEC=No or,

#DNSSEC=Allow-Downgrade,

Either way "Uncomment the line" (Take out the hash) and make it equal to off. ex) ..

DNSSEC=off

Save and Exit Nano (Ctl+X and Y for yes) Enter

Reboot or ...

sudo systemctl restart systemd-resolved

That’s it. But remember, now you’re running DNS queries without DNSSEC which could create security risks. If you don’t feel comfortable with this, then roll back the changes you made to the configuration file and simply follow the below steps to replace ‘systemd-resolved’ with ‘unbound’.

Dear Myst,

Thank you for your post, we are currently working on this issue. :smileyhappy:

Reyhan,

I call BullSh!%$^t, How can a network programmer not be able to fix a simple "Networking" problem like this,

in Laymans terms, Reconnecting or restarting or repopulating the network when it GIVES the Fatal message ...

"No Connection"

SERIOULSY!!!!!

Rocket Science - I think NOT! Does TeamViewer care? - Obviously and hypocritically NOT!

p.s. and TeamViewer is so proud of TeamViewer 13 - but only for PAYING Customers in the Beta Stage, and the webpage is seriously a dog's breakfast trying to get you to cough up >$1,000 for a subscription.

Trying to help, believe itor not, Mark

Thanks, @ack0329 ! I confirm it works on my Ubuntu 16. But why wouldn't the TeamViewer team fix it finally??

ack0329

Same problem after Upgrading to Ubuntu 17.04 Beta, but i was tired of paolying around with network connections hoping it would fix itself in the final version.

and, this worked for me after 2 weeks of giving up. 
It won't survive a reboot though, but it is a temporary fix.

sudo teamviewer daemon stop
sudo teamviewer daemon start

I hope this helps, Mark
Ubuntu 17.10 Beta with Gnome

ack0329

After solving the issue as per my previous post, I had some other network issues from my messing around with it and I re-installed Ubuntu-Gnome 16,04.3 (the newest of course) and ...

All is fine now.

(perhaps uinrelated but logging into the "Default" session instead og Gnome or the other 3rd one solved some issues as well - heck if I know why, but it may be worth a try)

peachstateboi

it is also happening on windows as well

Trolf

Same problem here with Ubuntu Gnome 16.04.3.

Re: Not ready. Please check your connection in Ubuntu

Here ism a solution for general network (DNS, Server, Connections, Loading, Teamviewer ...) issues which solved the Teamviewer "Not Connecting".

I realized that this issue was originating from a service called ‘systemd-resolved’. This is a DNS caching and validating service that comes pre-installed with Ubuntu 17.04

The solution came from this website

https://www.hecticgeek.com/2017/04/ubuntu-17-04-systemd-dns-issues/.service NetworkManager status

Go to the Update section half way down

Same problem here

mgogala

Running 17.04 and having the same problem. I ended up removing it and installing it on my Windows 8.1 VM.

meduzapat

same issue, after a restart (I normally never do, but updates asked) the "computers screen" failed to connect, I did a sudo service teamviewerd restart and everything is ok now.

dwheale

This works for me. I'm having the exact same issue and I'll use this until a proper fix comes out

vicsanca

Same problem in xubuntu 16.04.

sudo service teamviewerd restart solves the problem untli next reboot in my case.

Reddywretch

I have also had this problem. On both the .deb and tar.gz.

Installation works fine, and can connect to TV servers just fine when signing in.

Upon reboot, however, I cannot sign in. It is as if the sign in button isn't functional. That's the best way to describe it.

ndroftheline

the unsupported tarred version runs and connects fine. thus showing it's not actually a problem with my internet connection.

ndroftheline

same problem. running ubuntu 16.04, using lxde.

karls

I just installed v12 on my UbuntuMate 16.04 system as I am going overseas I want to have access to my PC for banking purposes. The problem is I just get Not Ready. Please check your connection. and my connection is fine, as I can surf, view the internet, email, whatsapp, even post this message from the same PC. It also keeps popping up a dialog asking for proxy settings, when I am not using Proxy. It's PC, Switch, Router, ISP.

Is there any idea of when this problem will be resolved? I am leaving in less than 1 day.

Shevchuk

Seems to be working for me now. I know there is an issue with Wayland, but that was not my case (using Xorg).

Shevchuk

Having the same poblem. Nice to hear that you are already working on it, any ETA?

Reyhan

Dear Myst,

Thank you for your post, we are currently working on this issue. :smileyhappy:

Myst

Really? No staff can help me with this?

Myst

I am using LXDE as my desktop environment and it works under xrdp but not teamviewer.

I have tried this with both Teamviewer 11 and Teamviewer 12 and both give the same issue.
