I'm having the same issue. I notice that when I go through the setup again via command line ( sudo teamviewer setup ), I am able to connect. I've tried everything I can think of short of wiping the OS: - Checking logs - Restarting the TV daemon - Disabling, restarting, then re-enabling the TV daemon - Setting a password - Combinations of the above mentioned with and without sudo While I could write a bash script to automatically enter in the credentials during startup, that really isn't a good solution to this problem. When I restart my raspberry pi, the teamviewer daemon is running, I get a notification on my Windows PC that the raspberry pi has signed in, and yet I can't connect without going through the setup process on the pi (via something like SSH). This is all happening on a headless raspberry pi without a monitor.
