supabase.auth.sign_up failing recently (used to work perfectly)

Bug report

• [x] I confirm this is a bug with Supabase, not with my own application.
• [x] I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

{"detail":"Email address \"firstname.lastname@pm.me\" cannot be used as it is not authorized"}

To Reproduce

Try to sign-up to https://www.techtonique.net/

Logging-in works as it used to. Signing-up has been working until today.

When inspecting the back-end, I'm able to see that the error precisely comes from the instruction: response = supabase.auth.sign_up({"email": email, "password": password}):

INFO: 127.0.0.1:xxxx - "POST /signup HTTP/1.1" 400 Bad Request

Expected behavior

Successful sign-up. Status 200 OK.

Screenshots

System information

• Browser (if applies) [e.g. chrome, safari]
• Last version of supabase, always (should I change this and fix the version instead?)
