Did not help... no clue what is going on here.
I even rebooted after just to be safe.
Cleared cookies, private/incognito, etc multiple browsers all same issue with the two users.
I had my colleague try the two logins from his Edge and Chrome browser, and he can log in no problem.
He is in the same office as me, same network, both on Windows 11.
This is a really strange issue, not sure where it would be stemming from.
