We believe Lync does not handle certificates that have a wildcard entry as the CN very well. Re-create the certificate using the FQDN of the Meeting Server as the CN. This does not need to be a public certificate in most cases: create a signed certificate with OpenSSL or a Microsoft CA server. Then upload the CA's Public Key to the Lync FE Server's Trusted Root Certification Authorities folder.
