TeamViewer11_Logfile shows unknown connection after enabling 2FA

[svom5P]

Hello all, despite changing the password and enabling 2FA, the TeamViewer11_Logfile shows a connection from another country (where IP: 25.xxx.xxx.xxx).  However, this is not listed in the Connections_Incoming log. Should we be alarmed? Is there documentation on how to decipher the Teamviewer11_Logfile?

I've not seen any documentation on the logs

I may well be a 'heartbeat' connection back to the TeamViewer servers (all around the world) to tell them that your connection is live...

What matt said is probably true. Do a reverse DNS lookup of the IP (ping -a xx.xx.xx.xx) and check if it's one from TeamViewer.

If it isn't from TeamViewer check if you have enabled incoming LAN connections and if you do but don't need that disable it.
In the logfile you normally have something like "Connection incoming, ..." when someone connects to your PC. If whoever connected was able to enter the correct password the logfile should also have something like "CPersistentParticipantManager::AddParticipant: ..." in it.
