vSphere Replication is Inaccessible After Changing vCenter Server Certificate

If you change the SSL certificate of vCenter Server, you cannot access vSphere Replication.

Problem

vSphere Replication uses certificate-based authentication to connect to vCenter Server. If you change the vCenter Server certificate, vSphere Replication is inaccessible.

Cause

The vSphere Replication database contains the old vCenter Server certificate.

Solution

1. Power off and power on the vSphere Replication appliance.
   vSphere Replication obtains the new certificate from vCenter Server when it powers on.
2. (Optional) If you configured vSphere Replication to use an external database, log into the virtual appliance management interface (VAMI) of the vSphere Replication appliance and click Configuration > Save and Restart Service.
   Do not change any configuration information before clicking Save and Restart Service.
   vSphere Replication restarts with the new vCenter Server certificate.
