Unable to remove ghost shared server - not visible in settings

Server name: IllegalSeagull (Guacamole)

Issue: Ghost server appears on all devices with spinning connection error

Already tried: Logging out, clearing cache on all devices

Server is NOT visible in Manage Library Access or Authorized Devices

Note: The server was recreated later with the same name, but both the live one and ghost server show up.

Request: Need backend database removal like in this resolved case

That was actually a shared server, not your own.

Yes. It is a server that was shared with me, and no longer exists. The server was recreated and shared again, but I show both as you see in the screenshot. I cannot get rid of the one that no longer exists.
