We are currently using version 5.6.3. We are able to connect to some of our services, but others are crashing Visual Cron. I can successfully pull up and use the services in WCF Test Client and in our applications. The services do work. However, a handful of them are giving the following error when trying to connect:
Connection failed with error 'Socket error: Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host.'
In the error detail, I see:
System.NullReferenceException: Object reference not set to an instance of an object.

There is nothing significant in the logs. I am at a loss. Does anyone have any insight into what is going on? Thank you.
