Hello,
I would recommend you opening a support ticket, because this problem can be many things, that seeing into the logs can be clarified. But we do not do that over the forums.

Please create a ticket and share ID here if you like.

A few common things to check:
1.- The account your are using to connect to vCenter has all the required privileges, and extend to child, etc.
2.- The Proxy you are using is inside the VMware Cluster you are trying to backup, if want to use HotAdd. If NBD, the proxy should see all ESXi by IP and fqdn.

But as said, always better a support ticket, please.
