Post-Plex Apocalypse: Plex doesn't see TNAS server

[rmar82]

I like many other Plex users got that message earlier today about needing to reset their password.
After doing so and signing out of all devices, I have no longer been able to get Plex to see my TNAS.
Uninstalling/reinstalling, rebooting, permissions, trying an older version, etc. None seem to work.

I don't get the 'reclaim server' option that I see many people mention elsewhere.

Has anyone else run into this situation and if so, know how to fix it so it sees my TNAS again?
I've spent several hours on it and am frustrated, about to give up.

3. Rename the plex shared folder；
4. Enable plex in the app center.
If it still doesn't work, please provide screenshots of the error.
