When I run the NRP (docker install on Ubuntu 20.04), the server status is red. Restarting the NRP or the computer does not help. There are no errors shown.
I do not know what could have caused the issue, I have already been using the NRP without problems today. So I will tell a story of other weird things that happened shortly before:
I have been using the docker NRP with a virtual coach from within the backend container without problems for some time. Then, for about a week, I did not use the virtual coach that much, I was mostly modifying transfer functions from the web cockpit. I only used the backend container to modify the bibi file of my experiment. When I finally returned to the virtual coach and wanted to run a script, it turned out that many python packages cannot be imported due to some missing dependencies.
pip check command within the backend container showed several dozens of missing packages, even ones that I have been using regularly before. I have installed them again (using pip) and now everything gets imported nicely. But I cannot launch the simulation due to the unavailable server.
I would be grateful for your help.
