Describe your issue
CodeChef has become almost entirely unusable. It can take forever to login; lessons take forever to load; pressing “Run” or “Submit” will result in “502 Bad Gateway” errors; and more.
And even if you manage to get through all of those errors, often times the grading engine makes mistakes, usually for silly things like not naming your variables the exact same as in the lesson, even if the logic works fine.
TLDR: CodeChef’s site and cloud engineering has gone to absolute crap and is virtually unusable. Even if the site works, the code grading logic is often wrong.
