I am a new user and thus far have been unable to successfully try any courses. I can load the webpage and the instructions, and get to click through all the 14 little pop ups. After that, no amount of waiting will get the rest of the terminal, simulation, and then the notebook also loses connection.
I looked at other issues, and it seems to apply to all courses I have tried, and I am on a stable, wired connection.
If this has anything to do with the “non-default” port comments (I am behind a firewall), IT requests more precise information so that we can implement a fix.
