SMTP confirmation emails not being sent
authHi everyone,
I’m having an issue with Supabase Auth confirmation emails only when Custom SMTP is enabled.
When Custom SMTP is disabled, confirmation emails are sent normally using the default Supabase email service.
However, as soon as I enable Custom SMTP, emails stop being sent and I get the following error: Failed to send confirmation email: Failed to make POST request to "https://<project-ref>.supabase.co/auth/v1/magiclink"
The user is created successfully, but the confirmation email is never delivered.
There are no visible frontend errors, and the issue happens in production as well.
Has anyone experienced this before or knows what could cause this when using Custom SMTP?
Are there any specific SMTP settings, ports, or redirect URL configurations that commonly cause this issue?
Thanks in advance!
