We are having some trouble getting TeamViewer's update mechanisms to work. Recently we added a policy to a few of our TV Host clients, telling them to automatically check for new versions every 7 days, and automatically install any that they find. However, nothing is actually updating. Also, if we run the "check for updates" command manually (with an admin account) on the test client, nothing happens at all.
I don't see any signs of our Sophos antivirus blocking anything. The perimeter firewall reports nothing regarding blocking access to any downloads. Windows Firewall isn't complaining, either. I don't see anything in the TeamViewer logs that pertains to update activity, either.
The test clients are on TeamViewer Host version 15.9.4.0. I am completely stuck as to what is going wrong...
