Jupyter server not starting
If you are greeted with a blank page after logging in, it most like means that your Jupyter server has stopped working. In most of the cases the simplest fix is to restart the server. You can do this by going to https://jupyterhub.apps.stack.it.ntnu.no/hub/home (or {coursecode}.apps.stack.it.ntnu.no/hub/home for specific courses) and clicking "Stop My Server" and trying again.
