Supabase auth rescue

Supabase auth redirects to the wrong URL after domain change

Supabase ties auth flows to specific redirect URLs. Moving your app to a new domain without updating those settings breaks every authentication path.

Domain Supabase VPS

What is probably broken

Login and signup worked on the old URL. After changing the domain, every auth flow redirects back to the old address or returns an error.

What production should look like

Auth flows working on the new domain with correct redirect URLs, OAuth callbacks, and email templates.

STEP 01

Find every Supabase auth redirect setting

Supabase has multiple places where redirect URLs are configured.

Check Site URL and additional redirect URLs in the Supabase auth dashboard.
List OAuth provider callback URLs (Google, GitHub, etc.).
Note email template redirect links (magic links, password reset).

STEP 02

Update Supabase for the new domain

Add the new domain to every Supabase auth setting.

Update Site URL to the new production domain.
Add new redirect URLs for each auth flow that needs them.
Update OAuth provider callback URLs in both Supabase and the provider dashboard.

STEP 03

Update the app and test

After fixing Supabase, the app also needs correct env vars and a rebuild.

Update Supabase URL env var on the server if it changed.
Rebuild the app and deploy the new build.
Test login, signup, password reset, OAuth, and magic links on the new domain.
