If I may add:
- Sign out your local browser from Plex/Web
- SSH tunnel to it
ssh -L 8888:127.0.0.1:32400 ip.addr.of.remote
sign-in
let sit idle
- back on local browser
- open incognito window
- http://127.0.0.1:8888/web
- Now you can sign in and claim it.
Should this fail,
- Stop remote Plex using the currently idle ssh session.
- Delete Preferences.xml
- Start remote Plex
- Repeat the above sequence starting at step 4 above
