Update: I have found this issue has nothing to do with section access. I can load fine with or without section access several times but after that I get the error "Cannot Open File" even though all my QVDs are there and have loaded successfully before that.
If I delete the app from the "Work" section, Duplicate it from the stream, then close the hub for about 15 minutes and then reopen it will again work with no issue. I am assuming this is some sort of bug with Qlik Sense.
Further, I am now running into the same issue with a file that is ONLY in my "Work" section (not deployed to a stream). However, the workaround mentioned above doesn't wok. It no longer will load at all even though I loaded it several times successfully today.
Anyone have any ideas as to why this happens or how to fix it?
I have an update on this in case anyone experiences the same issue. After working with our server team they found the reason this was happening. I no longer have issues reloading
Earlier, it was configured only with Central server node NOT Rim node. (requests which were going to Rim node was failing earlier)
We configured QlikSense services to run with service account on both the nodes.
