I am trying to upgrade from ECE 3.6.2 to 3.7.2. The upgrade runs, then tries to contact a host that no longer exists.

On the ECE summary, it has 9 healthy node, and 1 red unhealthy, but when you click on it, it says nothing matches.

On the hosts page, is says 10 total servers, but only 9 servers are actually listed.

The additional host was temporary and added for a migration, but it was removed, and deleted, but the deletion appears to only be partial.

How do I delete the reference to that server if it doesn't show up on any of the pages?
