Supabase signUp returning AuthRetryableFetchError 504


I have an application built in Next.js with Supabase.

It uses Supabase methods for sign up and login. Login works normally, but sign up stopped working (it worked as expected 3 days ago, but now not anymore).

...

console.log(validation); 
/* {
  success: true,
  data: {
    password: 'test',
    repeat: 'test',
    email: 'test@test.com'
  }
} */

if (validation.success) {
     const { email, password } = validation.data;
     const { error } = await supabase.auth.signUp({ email, password }); 

     if (error) {
        console.log(error);
        console.log(JSON.stringify(error)); // {"__isAuthError":true,"name":"AuthRetryableFetchError","status":504}
        return {
          message:
            error.status == 504 ? `Please try again later.` : error.message,
        };
     }
...
}

I checked in my Supabase database and I am getting that project status is okay and everything with auth. auth project status green

User can be added to Authentication table normally (using Supabase dashboard, manually), but through code, in my app, I always get error {"__isAuthError":true,"name":"AuthRetryableFetchError","status":504}. Console is empty or doesn't give any useful information.

What can I try next or how to fix this?


Solution

  • The problem was in my SMTP provider - Resend. Their servers were down. You can check it here.

    resend servers status

    The solution was to disable email confirmation in Supabase Authentication -> Providers -> Confirm email (as long the Resend servers were down).

    confirm email disabled
