Hi there @codexitos welcome to the community!
That’s bizarre this seemingly came out of nowhere as I suspect it’s do to a misconfiguration in application code. This is typically caused by setting the incorrect issuer (i.e. https://https://auth0-domain.us.auth0.com/) on the Auth0Provider or similar interface in the SDK you’re working with. The issuer defined in the configuration linked is what’s used in validation of the ID token - Omitting the issuer will default to the domain which should avoid this issue as well.
Hope this helps at least give you an idea of what might be going on!
