Don't see Server option on WD NAS

Did you reclaim your server since you reset your password?
Keep in mind you need to access the server through the bundled version of Plex Web:

  1. open the NAS’ local IP from within the same network → http://[PR4100 IP address]:32400/web
  2. go to Settings > [Server Name] > General
  3. click the Sign In button on that settings page (next to the “This server is unclaimed…” message)

Alternatively you can use a script like the one linked below to reclaim your server.
