Command Line Course Completely Broken

https://www.codecademy.com/courses/learn-the-command-line/lessons/navigation/exercises/your-first-command

I was practising on the command line provided in this course. In the process, I deleted everything on my Access Level.
I reset the page and now whenever I go to this particular course it says it’s unable to connect to Codecademy.
But on other courses, this problem does not occur.

It looks like the project just timed out or perhaps you lost internet connection? Refresh your page and that should fix it
