OK, I stand corrected on the authorized devices page.
This is a server I had in operation for years, I did not have a plex pass for a few months now and the server was not running, but it still is trying to connect to it from the web client and says it is not available, which it is, on the same network and same subnet.
It actually IS claimed, I just checked, it is listed under authorized devices, it mentions something about 3 h (probably last accessed, except that I know that must be false, because it has not worked for days)
Webclient mentions:
The server “name of plex server” is unreachable. Make sure it’s running, double check your network, and try again.
