Description of the issue
If I connect to that PC, no one after me is able to connect (including myself).
If I (or others) try to connect after the end of another connection, the TeamViewer of the user who is trying to connect displays WaitForConnectFailed. That message is displayed after 30-45 seconds after the connection attempt.
The user receive the same message after seconds, minutes, hours and even days between one connection and another.
The network configuration of the PC is correct.
I tried to disable IPv6 Configuration In Control Panel\Network and sharing center as specified in the TeamViewer troubleshooting guide.
Despite all of my actions, I was able to fix the issue only uninstalling and re-installing TeamViewer, but even in this case, TeamViewer accepts only one connection.
It seems like, after someone connects to TeamViewer, nobody else is able to do the same.
How can I fix this issue permanently?
