Whenever I open any challenge in “JavaScript Algorithms and Data Structures Certification (300 hours)” my browser(Firefox) has no internet anymore but when i cut it and open it again the net is working properly,
Js challenges have a bug that are doing something to browser
I suspect that there is an issue with your browser.
I’d try
- Disable extensions - one of your extensions could be interfering with the editor or tests
- Clear your cache - you might havo gotten stuck in a bad state
- Use incognito mode - a combo of 1 and 2 essentially
- Use a different browser - sometimes it’s an issue with your whole browser
