When I tried to make a connection to the Qlik Sense app I was getting the error message: "Error Request has been purged due to connection errors". If I turned off the Fire Wall I still get an error message. But this time: "Error Object reference not set to an instance of an object".
It might be obvious but - did you allocate token in QlikSense for user who is running QlikSense service?
