We do have the ame issue. It started abou 1 or 2 weeks ago with a few partners.

-> Right now, we cant connect to anyone. Message: "Unknown Error"
-> We were unable to log into our TV account for 30 Min

Tel Support Line is busy.

We cant work here....

These problems are increasing constantly.

We are customers since the first version and over the years the service is getting worse and worse and the prces are rising constantly..

Time to look for another remote solution.

Same problem here, cannot connect more than 10 users in 4 countries.

The status update website does not seem to reflect the total unavailability of teamviewer service.

Same problem here, i can't even connect to systems on my local lan...

And systems i was on a few minutes ago i try to reconnect suddenly give 'Reason Unknown'.
I mean it's standing 1 room away...

This has been going on since 26/10/2018... when will the issue be solved?

Hi Teamviewer peeps :-)

Cheers, Björgvin/Vegagerdin

Still getting some random 'Reason Unknown' here ant there, hopefuly this will resolve itself after a restart.

Michiel

Same, can't get through to helpdesk either, not likely they will be able to do anything.

I reported the problem. Still no answer. The call center is always busy

Since last friday (around 16:00 NL time) we've been having issues connecting to customers.

Today i'm still getting a lot of 'Reason unknown' replies when trying to connect. Abd frankly this is getting annoying our customers are located around the globe and i can't just 'drop by'.

When are these issues solved!?

using teamviewer in osx

Teamviewer Support suggested a complete uninstall and reinstall:

1) Uninstall TeamViewer from the Control Panel > Programs & Features

2) Delete the TeamViewer folder at below.
C:\Program Files (x86)\TeamViewer
%appdata%\Teamviewer

3) Delete the TeamVewer keys in the Registry:
HKEY_LOCAL MACHINE -> SOFTWARE -> TeamViewer [32 bit OS]
HKEY_LOCAL MACHINE -> SOFTWARE -> Wow6432Node -> TeamViewer [64 bit OS]
HKEY_CURRENT_USER\Software\TeamViewer
(*Deleting other important keys in registry may cause a serious problem to your computer.)

4) Download TeamViewer and install

Unable to connect my partner computer. Problem shown me reason unknown.

AlexFogerty

As I haven't received a reply from TeamViewer on here I have opened a support ticket with them directly. I will let you guys know what the resolution is when / if I get one.

AlexFogerty

I'm seeing it too. It has only started doing this in the past 30 days.

Silip tekrardan kurmayı deneyebilirsiniz. Kimi zaman temp dosyalarını da temizlemeyi unutmayın.

Teşekkürler.

I use free license version of Teamviewer (13.0.6447). I have seen same error there occasionally.

Suddenly this morning, non of our service desk analysts could connect to users workstations with teamViewer. We have a 7 session license, and support 9,000 workstations/users. This morning, all of our SD analysts had an issue, where they couldn't connect to any users workstations, via TV ID, or hostname or IP. The popup box "Unable to connect - Reason unknown" was being shown to everyone that tried. We're using the latest v12.0.80984 C client
