I cannot answer your primary question, but can say that you can get the monitoring apps from qlik\sense\apps\ on the server. They will be named by their GUID which, under better circumstances, you could get from the Apps page of the QMC . In the current situation, though, I would just take all the apps.
You can copy those files to a local machine running Sense desktop (or Server) and add .qvf on the end to open them.
have you tried contacting the well know Tom Mackay ? kidding
- Ensure you have IE10+, Chrome, Firefox
- delete your browser cache
- go to QMC, go to users and elevate their role to a content admin for example and retry the test
Were you ever able to resolve this issue. I am having the exact same problems with Sense 3.1. I have been working with Qlik Support for over 2 weeks now and they also cannot resolve it. I can sometimes get the hub to load if I restart the QlikSenseServiceDispatcher service, then go to the QMC first and then replace QMC with HUB in the browser. Obviously this is not ideal.
