How do I troubleshoot challenge and submission issues?

All courses come with a built-inHints section. You can use these to work through the challenges. There are solutions available on our community forum as well.

Other Solutions

  • Try using a Chrome Incognito Window and see if that clears up your issues.
  • If you are behind a VPN or Firewall, it may interfere with playing courses.
  • Clearing your cache and local storage may help, as well.
  • Enable 3rd-party cookies, namely for [*.] This is necessary for the Node and Express courses.
  • If issues persist then you can also try a different browser. This will sometimes help here.

Some of our newer courses use advanced browser features. This is for for caching content and using local storage. We sometimes run into issues validating code when users are running Browser Extensions. Some of these include: AdBlock, HTTPSeverywhere, DoNotTrack or ModHeader.
