Lost federation connections after installing new certificate

Question

After installing a new NIC for the egde external connection and new GoDaddy 10-slot UCC cert on my edge server and Forefront TMG reverse proxy, I have lost the ability to connect to my federated partners.  Snooper logs seem to indicate that the
certificate is not being accepted.  Test-CsFederatedPartner returns the message, "This machine does not have any assigned certificate."  Running the Lync Deployment Wizard on the edge shows that it definitely does have a certificate.  Get-CsCertificate,
Test-CsComputer, and Test-CsCertificateConfiguration all show the new certificate is in place.  Digicert's online certificate check has no problem finding the edge server and has verified that the cert is functional.  This edge server was running
perfectly for over a year.
I'm stumped.  Thanks in advance.

Hi,CJADuva,
Did all your other external access such as external user login and download address book or meeting content work normally?Just the federation broken?
What the SN and SAN entries of the new GoDaddy UCC certificate?Do they meet the external Edge certificate requirements?Check the following links for Edge certificate requirements

If all are ok,please ask your federated partner to check if the Godaddy CA is in their trust CA list,also I remember that Godaddy always has intermediate certificate,please check if you and your partner has installed it too.
