Environment

VMware Site Recovery Manager 8.3.x
VMware Site Recovery Manager 8.5.x

Resolution

Remove com.vmware.vcDr from vCenter MOB. Refer to Cannot remove or disable unwanted plug-ins from vCenter Server and vCenter Server Appliance for removal steps.

Additional Information

Remove SRM and vSphere Replication extensions from the MOB and register again. Only remove the extension of the appliance that is failing to register.

com.vmware.vcHms

com.vmware.vcDr

You might run in to the same issue after repointing the VC to a different sso domain - but SRM server did not log anything in /var/log/vmware/srm/drconfig.log
