Problem starting assignment

I am experiencing a problem loading the C1W1 assignment. After clicking on “Launch Notebook” I get a new page with a progress bar showing that the content is being loaded, but it gets stuck at 50% and after a while I get an error message:

I have tried multiple times using Firefox or Safari, Linux or Mac, and after clearing cache and cookies. It may be a problem on the server side, or somehow a configuration issue on my side.
So far I haven’t encountered any issue running the previous C1W1 labs.
Help would be greatly appreciated.
Many thanks
