Unable to continue coding challenges

[shabbas]

Describe your problem and - if possible - how to reproduce it

After signing in, when i click on "Go to the coding curriculum" button, it takes me to https://learn.freecodecamp.org/responsive-web-design/basic-html-and-html5/add-images-to-your-website which always appear broken. I have tried this on Chrome, Safari and Firefox but the page did not load anywhere.

I dont use any proxies and do not work on this when i am connected on VPN but i still face this continuous error.

Add a Link to the page with the problem
