I am having most of the time problems accessing the CS50 IDE (sometimes it works).

I am using chrome and after I log in with my github account, it is always stuck on the "cloud 9" window and giving me the message "This is taking longer than expected. If you think there might be an issue, contact AWS Support."

I tried:

  • restarting browser
  • restarting computer
  • cleared cache and cookies
  • doesn't work in internet browser (not sure if that is intended, just stays in "preparing your environment)

The status page shows that it is all operational, so I am not quite sure what could be wrong..

UPDATE: status page was updated and the problem is coming from AWS: "Investigating - It looks like AWS Cloud9 (the base software for the CS50 IDE) is experiencing some issues at the moment. We have reached out to their team to investigate."

Thanks for your help!

  • According to the status page it is a system-wide problem. Apr 21, 2020 at 15:20
  • Thanks @DinoCoderSaurus, they must have updated it after I wrote this post.

I've been having this problem too the whole time I have been using ide. I usually refresh, go back, or go back then back forward. When those don't work I usually retype the website in and it comes back.
