Partner could not be contacted at the given network address

Hello,

I've been having a problem with connecting to other computer. Teamviewer has been working just fine for a week or so, but then I started recieving errors - first was that TV was not running on the other computer (which I am sure it was), and now I simply cannot connect at all with the error saying that "partner could not be contacted at the given network address"

I tried disabling IPV6, but no change.

Here's what the log file says:
