Environment

VMware Site Recovery Manager 8.x
VMware vSphere Replication 8.x

Cause

Site Recovery Manager is not able to resolve vSphere Replication FQDN.

Resolution

Login to the vSphere Replication appliance: https://FQDN:5480
Change local host in reconfigure in vSphere Replication wizard from FQDN to IP.

- Perform the above step on alternate vSphere Replication site.
- Reconnect in Site Recovery UI

 

Additional Information

Note: If the IP address cannot be used for security reasons, then the hostname and the certificate need to be reset using lowercase for the FQDN of the VRMS appliance:

 

          Example : use vrms1.example.com instead of VRMS1.example.com
