The following exception occurred at Microsoft.Rtc.Internal.Chat.Server.ServerCommon.MgcServiceBase.createAndStartServer () and Microsoft Lync Server 2013 persistent chat failed to start

First check the port of the persistent chat server, which is 5041 by default. You need to check the status of all the servers in the pool and the status of the member servers in the topology in the control panel.
