Learn Bash by Building a Boilerplate - Build a Boilerplate

Tell us what’s happening:
Hello, I’m just wanting to start the Build a Boilerplate course, but it’s not working. I click on “start the course”, Then it asks me to login, I agree to the terms and login using GitHub, and then it redirects but just stays blank. I have cookies allowed and have given permission to the site. Anyone having this problem and resolved it? Thank you!

I’m using Safari and have tired this on Brave.

Sometimes it is slow and works after a bit. And sometimes I have to reload it.
Have you tried a few times?
