Hello,
I recently performed some maintenance on 4 host cluster and after rebooting none of them connected in vcenter after 20 minutes. I was able to right click and choose connect and the hosts did connect with no issue. I rebooted again to test and the same thing happened.
What can I look at to see why this is happening? Logs don't seem to reveal much to me. Also Name Resolution is all good as I understand that can cause this so I checked it out and its fine both forward and reverse.
Thanks
