The SMS_ISVUPDATES_SYNCAGENT.log is showing "Unable to Connect to local WSUS Server" every minute ans has been for days (the log only goes back 3 days and it's full with these messages). I recently performed an in-place upgrade from 2012 R2 to what is now 1910 with Hotfix. So far everything seems to be working as expected but notices this last night and I'm not sure where to look. I can connect to the local SQL DB where WSUS DB is located and connect to the SCCM DB as well.
