The simulation and shell is not working

I cannot use the course page because the simulation and shells are not loading. It shows “bad gateway.” It has happened since yesterday. Can somebody fix this problem?


Could you indicate the course and unit you were in please? The browser you were using? The internet connection speed?
It would help us isolate the issue and maybe give you some indications.

That issue could happen sometimes if the internet connection is not stable or the browser is not supported
