Lync 2013 Edge replication not working

Question

hi, I have a Lync 2013 Edge replication issue - it is simply not working.
UpToDate           : False
ReplicaFqdn        : LyncEdge.contoso.com
I have already checked the following:
1) telnet from FEP servers to the Edge sever on port 4443 is working
2) Certificates are installed correctly - Lync Federation, Voice/Video to Skype, Lync Mobile is all working fine.
3) Replication traffic checking showing the following error in XDS logs:
(000000000126DB35)[FileTransferTask(11, 9/03/2015 2:44:24 PM): {TASK_NOT_STARTED, fromReplica, [lyncedge.contoso.com, HttpsWebService, 4443], 0}] Failed to copy files from replica. Exception: [System.ServiceModel.Security.MessageSecurityException: The HTTP

I have checked certificate stores: there are only 34 certificates in the Root folder and the SendTrustedIssuerList reg. key has been configured, which did not solve the issue.
Any idea how to troubleshoot this or possible root causes?

Try Test-CsComputer on the Frontend Servers and the Edge Servers. This should check Windows Firewall exceptions are correct. Then check permissions on your Lync fileshare. You can also try to reinstall CMS Database with the following command (user must be
memeber of CsAdministrator group and sysadmin group of SQL Server)
Install-CsDatabase -CentralManagementDatabase -SqlServerFqdn CMS.FQDN 
-SqlInstanceName DBInstance -Verbose
