SCCM Cloud attack CMG error after restore

Question

We had a HD fail in our server and restored SCCM from a backup. We are running current branch. The issue is that in the CMGatewayNotificationWorker.log we are getting the error below. It is repeated over and over. Every time the CMGatewayNotificationWorker starts it gets the same error. Is there something I can delete or do to remove this? I have removed the co-management, but can not remote cloud attached. The bgbmgr, CloudMgr, and cloudusersync have no errors and BgbServer only has errors dealing with client machines.
