User unable to create App - "no response was received from the server"
This is a new-ish installation of Qlik Sense, and one of my first users is unable to create an App.
The error they are getting is;
No response from the server
No response was received from the server when attempting to create the app. Please try again if the app was not created.
I have tried opening up the security roles - there is an role for App_* for !user.IsAnonymous() with the permission of Create.
It seems to me like there might be some sort of access problem on the server - do I have to change folder/file permissions to allow the users to create their apps? My server is running under system account and I can't find anything about this in the installation guides I have.
