Your server is now unclaimed.
You will need to reclaim it to add it to your account.
Unclaiming/re-claiming has no effect on your libraries, collections, etc.
Use the 127.0.0.1 URL @dbirch posted. That should get you to server settings so you can claim the server.
If that does not work, see: You need to reclaim your server, but don’t dare to touch the Windows Registry.
Internet connectivity is required to claim a server. The claiming process registers the server with plex.tv systems. If it cannot be registered, claiming will fail.
