Week 2 practice lab programming assignment not loading

I can’t seem to open the Programming Assignment: Week 2 practice lab: Linear regression jupyter notebook. I keep getting this error message I have attached to this post. I have closed coursera, logged out, closed my browser and even clearing my cache. All to no avail. Please help as I need to do my assignment so I can move to the next week

I am not a mentor for MLS, but just looking at the error message it looks like an “IT” problem: notice that the DNS server is saying it can’t find the IP address for that coursera.org hostname. Is this the first time you are opening an assignment notebook in this course? If not and you have successfully opened other notebooks before, then the next question would be “is anything different about the current situation versus the previous cases that worked”? E.g. that you are using a different computer or you are on a different network (now at school or work but you were at home before)?

If everything is the same and this is not your first notebook, then the next theory is that something is damaged about that notebook. If that is the case, then try getting a clean copy. Here is the procedure to do that for DLS notebooks and I hope the same method will work for MLS as well.

Here is what the URL should look like:
https://www.coursera.org/learn/machine-learning/programming/jsE7w/week-2-practice-lab-linear-regression

Note that it starts with https:// and includes a ‘www’.

Why does the URL in your image not look like that?

I’m going to guess that the error is due to your browser blocking a URL that doesn’t specify https.
