About a year ago I created an app to read some OIDC info (nothing complicated) I created a user and proceeded to testing it, and it worked like a charm.
Since then I left everything put for a while (a few months) until today, when I wanted to show off at work, and suddenly I cannot login as I used to. The auth0 login page is just never going away asking me constantly if I am the one I am.
I checked via F12 and I noticed that the login screen triggers a POST to https://.eu.auth0.com/usernamepassword/challenge
and that returns 404!
What is this challenge? I tried looking on communities and no one has this issue, I never set up any challenges, and there is no mention on how to change that ANYWHERE
please please help
