Remote connection is stuck at authentication
I have a computer that was configured for remote access who was working as intended until this morning. I can't access it physically until this weekend and I want to prepare for future occurrences of the following problem:
When I try to remote control the PC in question, it gets stuck on "Authenticating..." for both the desktop and phone app. Oddly, it is not asking for the usual TFA prompt with my phone as it was doing last night. The app is properly configured on both the controlling devices but I fear that the device I'm looking to control has forgotten my TFA and is looking for a, now, unknown phone. Is there any way to sync my TFA settings between all my devices remotely?
Also, I have rebooted the target PC once which, ostensibly, has restarted the service. Pings show the device is there and port forward is correctly configured. Everything was working until this morning but now I'm no longer able to authenticate on *only that device*. Any way to fix this remotely?

Hello @thecakeisal1e,
Good to see you posting again! ✨
As you already restarted the remote device (and therefore the service), my only suggestion would be to:
- Reinstall TeamViewer
- Reconfigure TFA for connections on the device
I can't see any specific reason it stopped working except that it's an unfortunate bug.
Looking forward to hearing from you.

Fwiw, I had the same problem. I deleted TeamViewer from Applications, clicked "Yes" on the TeamViewer pop-up that offered to fully complete the removal, downloaded a fresh copy of TeamViewer, installed it, and now it works as expected. The computer I did this on runs MacOS 14. I have established a connection with a computer running MacOS 15.

I wish I could say this helped me. It did not.
