Symptoms

Virtual Machine Image Recovery consistently fails using hotadd.

The NetWorker vProxy recover session log shows: 
159373:nsrvproxy_recover: vProxy Log: YYYY-MM-DDTHH:MM:SSZ ERROR: [34] Unable to open session to backup path device "datadomain_fqdn": "[5008] invalid argument".
ERROR: [34] Failed to recover to a new VM. [5008] invalid argument

Cause

NetWorker vProxy errors out while contacting Data Domain for recover whereas the backups are good. vProxy requires a handshake with Data Domain.

Resolution

Use NBD to complete the handshake. Run recover using hotadd.

Initially in vProxy before any change both NBD and hotadd were set to 25.

vProxy was changed to use NBD mode only by setting hotadd = 0 and nbd = 10.

See the screenshot below

Later on both NBD and hotadd were set to 25 now. This was tested successfully with multiple VMs.
