Object reference not set to an instance of an object.


The below image shows a common error on the Vuzion CORE interface, which is a known bug when attempting to synchronise from CORE to Microsoft;

The connection to Microsoft is closed by them, prompting in the logs for:

"The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.

System.Net.WebException: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. ---> System.IO.IOException: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond."

We have previously raised this to the developers of the panel who have advised that as the error comes from the Microsoft side and will occur randomly to any random customer - there is no workaround but to give the synchronization process time to finish.

There is no need to raise this to our support team as the connection is usually re-established within 20 minutes, if you see this error for longer than that please feel free to call in and report the problem.
