When we updated our Lync 2013 servers to new SHA-2 certificates.
Microsoft discontinued SHA-1 certificates for years already.

the log "[ERROR ] TLS: Unsupported signature alg 1.2.840.1135220.127.116.11 (unknownObjectIdentifier) in cert";
please issue maintaining release to support SHA-2
thanks for your feedback.
We'll report your request.
