AWS Cloud Technical Essentials exercise: is it broken?

Like a number of people I can't seem to get the EmployeeApp up and running on the freshly launched EC2 instance. User data for the launch includes the following line:

wget https://aws-tc-largeobjects.s3-eu-north-1.amazonaws.com/DEV-AWS-MO-GCNv2/FlaskApp.zip

I've ssh'd to the ec2 instance in question and running this command delivers the message "No such file or directory". It therefore doesn't seem surprising that the app doesn't run - though perhaps I haven't undersood something about how this is supposed to work. The next stages of the course appear to reply on this app working. I am therefore prevented from continuing. Please advise!
