Lync Edge Server Replication failed FALSE with red cross
In a Lync Deployment, where we have installed Lync Edge Server, we see the Replication is not healthy. You will notice a red cross or in the Management Shell the Replication is not UpToDate: False.
If actually have telnet to the Edge Servers Port 4443, you realize that the port is open and working.
As well you can test access the service itself:
Via this access, you also be able to validate the assigned internal Certificate and the Certificate Chain. If you encounter an error with trusted root certificate, you will end up adding it other Trusted Root Authorities.
Afterwards, you will still encounter the red cross, or false up-to-date status.
This is normal!
The Replication itself is working fine, but your Connectivity to the Edge is limited.
This mean we cannot query the service due to the SECURE CHANNEL limitation.

Problem is now solved...!
Set new Registry Key on Edge Server:
I was asked a few time, what acually is happened if the SQL Server shows a Red Corss.
This is failed topolgy configuration and should be validated.

You should also validated your Get-CsManagementStoreReplicationStatus. There should be not SQL Server shown.
