Unable to connect

Peter & Elspeth

I have a free licence running on both computer A and computer B. In the past I have been able to connect to either computer to the other but now can only connect from A to B, not B to A. Both A and B are running TeamViewer 15.81.5 (32 bit). I cannot say whether the problem occurred after a particular update as I don't try to connect from B to A very often. I wonder if the problem is that computer A is running Windows 11 while computer B is running Windows 10.

@Peter & Elspeth Has anything changed in the way A and B are connected to the internet (e.g., switched internet service supplier)? The most likely reason for the problem is that something changed in the environment. Has anything else changed in the hardware or software environment, especially on A. What is the exact error message (or behavior) when you try to connect B to A? Personally I think the Win 10/11 difference is unlikely to be the culprit. I am using 15.81.5 on Win 10 to connect to Win 11 with no problems.
