.....so randomly, my backup jobs started failing.
When I test credentials I get these errors now. Keep in mind it was working perfectly. I have already checked the obvious (credentials). It is not this. Something happened.....and I have no clue, as nothing changed in my infrastructure. I restarted vCenter, restarted the target VM being backed up, restarted management services on the vSphere host, restarted backup proxy servers....nothing is working. I have 2 backup servers and it's happening on both. This happened across the board on all backup jobs
regardless what account is being used (in some cases I use local creds on a server that is not domain joined).
Yes: the guest creds I am using have administrator rights
I am posting here because I feel like I have already covered all the obvious bases. What am I missing? Why would a backup job go from working perfectly, to suddenly the login failing and job totally fails.
