Error after database upgrade, Job Server Status error: "The underlying connection was closed: An unexpected error occurred on a receive."

Hi All,

This morning we had a DB upgrade from SQL Server 13.0.5893.48  to 14.0.3451.2. Running OneIM 7.1.3.

After restart the Develop system gave an error in the JobQueueInfo.net - Job Server Status - Job Server: The underlying connection was closed: An unexpected error occurred on a receive.

Anybody a clue?

Regards, Hans
