Error in Lab (Week 2 Assignment)

Week 2 lab is not loading. I refreshed it multiple time but still showing same error.

im having the same issue

the same here, have you found the solution yet ?

No, but Coursera staff is working on it. Once they resolve it, we will update you on this post.

well i look it up in another thread, i guess the server is not working properly right now and most probably will work after sometime.
