Hi,
Is VR server deployed using static IP or via DHCP?
I believe you are hitting a known issue:
Details
If the VRM Host field in VAMI is FQDN, you might experience connection issues if you configured replications within a single vCenter Server topology. You might also experience an issue with certificate validation if the vSphere Replication appliance is configured to accept certificates issued by a trusted Certificate Authority. The command host <VRM Host field value> returns 127.0.0.1.
Solution
Manually edit /etc/hosts on the appliance and remove association between the FQDN value and 127.0.0.1. Make sure to have another entry for 127.0.0.1 and localhost value in the file, as the appliance's embedded database needs this entry. Alternatively, set the VRM Host field to a literal address in the VAMI.
