Thanks David Lorenz ! That was it, ADDITIONAL_REDIRECT_URLS was set but I needed to remove "https://" from the URLS.

David Lorenz Thanks for the response! I’m not surprised everything is not working, Supabase self hosted is super finicky. Yes, the magic link / email verification links are returning 403 errors. This comment section won’t allow me to post links but API_EXTERNAL_URL is set correctly. The verification URL from creating a user through the dashboard: http://kong/auth/v1/verify?token=xxxxx... The verification URL from creating a user through the API: http://example[dot]com/auth/v1/verify?token=pkce_xxxxx... Its odd that kong is the url from the dashboard. I double checked Forced SSL, but the API link is non-SSL. I've also tried manually sending an SSL link but still get the 403 error.

This has been helpful with getting a newer version of Supabase hosted! I was struggling with getting Auth to work until you posted the Advance Tab settings for the dashboard. Now I can add users, but I'm getting a '403 Forbidden' error on the user verification links. Any ideas on what's causing this?
