Lync Edge - Unable to connect to federation port 5061

We can successfully connect to the edge server over port 443 but not 5061.  Port 5061 is open.  Here is the message We get when we try to test from outside.

Attempting to Resolve the host name sip.mycom.com in DNS.
Host successfully Resolved
Additional Details
IP(s) returned: 200.1.1.1

Testing TCP Port 5061 on host sip.mycom.com to ensure it is listening/open.
 The port was opened successfully.

Testing SSLCertificate for validity.
 The SSLCertificate failed one or more certificate
 Tell me more about this issue and how to resolve it

Additional Details
 If you are using a Reverse Proxy to get to the Access Edge Server, this could possibly be an issue with Reverse Proxy configuration.: Exception Details: Message: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

Testing SSLCertificate for validity.
 The SSLCertificate failed one or more certificate ....

At least it looks like a certificate error? Lync needs valid certificates anyway.
So either the external name is not in the certificate, or your client can not resolve it, means does not have the root certificate.
