Event ID 18456 - SQL Server 2014

Last Modified: 2016-01-08
This error occurs when the IIS site is reported as down, and the database cluster does not automatically failover the database. Running a network capture, but a main architectural issue is that the witness server for SQL Server 2014 resides on the mirror server, and Microsoft strongly recommends it being moved to a separate server.  Has anyone experienced this issue before?
