Port 902 is blocked on the ESXi which is registered under vCenter. Port 902 must be open for backup proxy to communicate with the ESXi. Backup proxy communicates with vCenter over port 443 and it communicates with ESXi host on Port 902.

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.
Initiate a manual backup and verify whether it completes successfully.
