The Persistent Chat server can not establish or maintain MTLS connection to the Lync Server.
This problem is usually caused by an invalid MTLS certificate configured on the Persistent Chat Server or Lync Server.
Review certificate related sections in Persistent Chat Planning and Deployment Guide. Ensure the MTLS certificates configured on the Persistent Chat Server and Lync Server are valid.
