Cannot add machines to replication on core - "hostname could not be parsed". (4039713)

Receiving the following error when adding machines to replication -

System.UriFormatException: Invalid URI: The hostname could not be parsed.

Create an export of HKEY_LOCAL_MACHINE\SOFTWARE\AppRecovery\Core\Replication\RemoteCores\

Once you have this done browse to:

HKEY_LOCAL_MACHINE\SOFTWARE\AppRecovery\Core\Replication\RemoteCores\Slaves\********-****-****-****-************\HostName=

Then confirm the host name matches the replication target core host name
