Lightning Lab Quiz Portal is not working

I’m trying to do this section in the course: https://cockroachlabs.udemy.com/course/certified-kubernetes-administrator-with-practice-tests/learn/lecture/18341304#notes

When I launch the lab and click “Lab Portal”, I get a webpage with a 502 Bad Gateway.

Is this a site issue?
