Hello,
I am receiving the same Events on my FE servers regarding issues with authentication. We currently have a case open with MS to figure whether or not this event is related to External communication failures between internal resources and external clients. So far we have sent them every trace/capture imaginable, but still no answers. This event seems to only occur when a internal user communicates with another user through the access edge server. The initial communication makes it to the destination, but the very next return message error's out with a "Time-out" error message. The weird thing is that the very next message sent goes right through without issue. When doing a SIP trace we get the following entries in the debug session
LogType: diagnostic
Severity: error
Text: Message was not sent because the connection was closed
Note that the very next conversation within that session goes straight through without issue, delay, or error's. Any assistance would be greatly appreciated. I will update this post with any updates from our MS Case.
Regards,
Michael Alexander
