The unsupervised learning course in the machine learning specialization week number 2 in the last practice assignment, when I try to access the lab it returns 404 error. It was working normally but when I closed it and came back later it is not working. I tried logging out, reopening it but no results.
I just tried it, and the lab opened for me without any trouble.

Hi. You may have renamed your notebook, and the lab can’t find the original file. If that’s the case, please refresh your workspace to get a new copy and work on the original file. The autograder will not accept renamed files. Hope this helps.
