I had stopped on Unit 4: Configuring a work party during the middle of the exercise. When I went back to finish a few days later where I had left off, the app login page does not load. I figured it was a temporary thing and continued with the next lesson, but trying again the problem is still there. I will attach a screen shot of the errors.

I tried opening in a new tab and window with different results (see image). I disabled pop-ups, tried Explorer, Edge, and Chrome browsers, resetting my PC, logged out of all sessions I had, and even used a different laptop. Still I have the same issue.

I was able to see the login screen for the exercise System with one direct link I had, but when I "logged in" all I see is a "logout" tab with a blank screen. Actually, I just tried getting a screen shot and got a new message (see second image). My colleague who is finishing the 7.2 version is not having any issues. I don't know what else to do. Help would be appreciated.
