Plex app on iPad "Uh Oh Something's Not Right" unable to access anything

Very odd indeed.

What worked for me was to:

  1. Stop Plex server
  2. On iPad, Delete iOS app
  3. Reinstall iOS app and perform initial login / setup
  4. Select alternate profile (if using same profile the error would come up even while server was offline)
  5. If successful, restart Plex server
  6. On a computer to go Plex Home, remove PIN from the user getting the error.
  7. On iPad, Kill Plex app on iOS and relaunch - try offending user without PIN, if successful,
  8. On iPad, Kill Plex app on iOS
  9. On a computer to go Plex Home, ADD PIN back to the user
