Login Form Not Submitting After Entering Username and Password

[juules26]

Hello!
I need help to keep doing my mooc python course: https://programming-23.mooc.fi/part-7/
I'm using Microsoft Edge, and it has worked for me until now.
Basically, when trying to log in, the placeholder text "username" and "password" remain visible in the input field and also doesn't load. Also, the exercises don't display and instead I can only see 'Loading'. But it never loads!

I tried to check if the exercises work from my iPad using safari, and they did load. So I am going to download other browser, but also I am not sure about which one.

I opened the console to see if there were errors and this is what I got:

I don't understand anything from there, but in case it's helpful to know what's happening.
Thank you very much in advance!!!!
