This might seem simple but I thought I would post it anyways. I always tell everyone to check the event viewer if there are unexplained errors or issues with the system. Recently, I was investigating random SOAP messages failing. REST services was working fine. I wasn’t getting any clear errors except that it was forcibly closed. System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. Problem: Where do I look in Event Viewer? In most cases I could guess which folder to look in under Microsoft > Dynamics. Solution: Create a custom view So, I decided to create my own custom view. Tick Critical, Warning and Error. Select the Dynamics logs only. Repeat the error and it should stand out.
