Allow Teamviewer in Web Protection

MiroslavCacija

Teamviewer used to work normally for a long time, but stopped recently. If I turn off web protection ( transparent mode ) it works. Tried every possible exception, but no go. Any ideas, anyone have similar problems ?

    Maybe related to the attacks they are getting at the moment.

    Monitoring - We were able to resolve the server load issue. TeamViewer services should be up and running normally again for most of our users. We will continue to monitor all systems in order to ensure mitigation is complete. We would like to apologize for any inconvenience experienced by our users.

    Update - The implementation of today’s precautionary measure resulted in a very high server load. A larger group of users are currently experiencing service degradation. We are working to resolve the issue and get our systems up and running normally as soon as possible. We would like to apologize for any inconvenience experienced by our users.

    Identified - Based on global cooperation against malicious cyber activities, TeamViewer’s team and leading security researchers perform regular threat prevention analysis to identify inconsistent or suspicious behaviour within and beyond its network. In this context, in-depth data analysis revealed patterns of connection attempts that deviated from expected usage scenarios of TeamViewer. As this observation was limited to a small subgroup of endpoints, TeamViewer decided to invalidate and automatically re-assign unique identifiers (TeamViewer IDs) within this subgroup.

    The precautionary measure has successfully been rolled out to full effect. For a short period of time, some users may experience service degradation, which will be resolved as soon as possible.

    They probably changed something on their side, as you said, I too see no errors in log etc. Are we two alone in this ? Anyone else using web protection and have problems with TV ?

    I regularly get this problem too that TV just doesn't connect. Today I dug a little deeper and strange thing is that I cannot even find any evidence in either firewall log or webfilter log that my host is even trying to reach TV.

    There's no evidence of traffic going to port 5938 in firewall (for some other hosts there is at the exact same time) and there's not any connection to find in webfiltering log for any host matching teamviewer in the URL.

    Sometimes it just works and sometimes it doesn't. At this time I just don't have a clue in why it wouldn't work...
