Cannot connect to Google Admin Workspace

[Stanley1]

I try to log in my Google admin workspace account (I am a super administrator). I validate to 2 steps verification on my phone and then it just keeps on loading. I tried these steps without any success : https://support.google.com/a/answer/6335621?hl=en&src=supportwidget0&authuser=0

The problem is occuring since more than a few days now.

Thank you for your help!
