Teamviewer Connection Blocked After Timeout Mac

Installed on 2 machines before going away for a while. One stopped responding in a couple of days, the other one is still up days later but when I log on it disconnects after (literally) seconds and then gives me the 'connection blocked after timeout' message for a long time. Completely useless software (at least the free version). I am using a free license to connect my work computer in an academic environment (I'm faculty at a med school) to my home computer. I've been doing this for several years without issue. All of a sudden, today when I first connected, the session quit after a few seconds and I got this message on my work computer: 'Connection blocked after timeout.
