Resolution

Try to telnet/nc from backup proxy to ESXi on port 902. Check if port 902 is blocked on the ESXi as backup proxy is not able to communicate with ESXi. For successful communication, open the port 902 on ESXi host.

Verification

 Initiate a manual backup and verify whether it completes successfully.
