When install the latest OnDemand, I can get most functionality to work including Matlab/X11. However when clicking on the button to open a shell (on the launch card) it gives a “Failed to establish a websocket connection. Be sure you are using a browser that supports websocket connections.”
This also happens when trying to get RStudio and other non-X11 apps working. Interestingly enough testing manually via a slurm allocation, using nc to listen on a port and them browsing to that node with OnDemand works just fine.
Basically the opposite of the problems I had when installing previous, but that is far more likely to do with me than anything else.
