TesthostVR01 : vSphere Replication Management Server could not establish connection to vSphere Replication Server at '###.###.###.###:443".
TesthostVR02: vSphere Replication Management Server could not establish connection to vSphere Replication Server at '###.###.###.###:443'.
TesthostVR03 : vSphere Replication Management Server could not establish connection to vSphere Replication Server at '###.###.###.###:443'.

 

Environment

vSphere Replication 8.x 
vSphere Replication 9.x
vSphere ESXi 8.x

Cause

Upon reviewing the ESXi host services, we noticed that hbr-agent is enabled and hbrsrv has been stopped for the hosts participating in replication.

vSphere Replication's HBRsvc is a core component responsible for the replication process of virtual machines. HBRsvc (Host-Based Replication), is a hypervisor-based replication engine that sends changes from the source virtual machine's disks to a replica at a secondary site.

Resolution

The hosts used for replication must have hbr-agent & hbrsrv running. Follow the steps below to check these services. 

From the vCenter UI select the affected ESXi hosts and click on Configure and navigate to Services 

Ensure the hbr-agent & hbrsrv services are running.

You can also start hbrsrv service on the affected hosts by running a command. 
SSH to ESXi host.Run the command : systemctl start hbrsrv
