I have a brand new installation of SnapCenter 3.0 (not upgraded) and I have the vSphere plugin installed on a separate server, I have message queueing running on both the SnapCenter server and the vSphere plugin server.
When I try to run a backup it fails instantly with the error "An error occured while adding job to jobQ: Message Queue service is not available." in SnapCenter, the job logs aren't of any help and nothing in event logs on either server.
Any ideas where to look next, there's very little information around on the web given this is a new feature with SC 3.0
Edit: Upon further investigation I am also getting this same error when attempting to run newly configured SQL Backups via SnapCenter, which points to the issue being with Message Queueing directly on the SnapCenter server itself?
