Self-hosted Supabase: "Invalid authentication credentials"

self-hosted

Hi

I'm running Supabase self-hosted (latest docker setup) behind a custom domain
I am setting the connexion page, when i use the rights credentials I'm having an issue where every request returns:
{ "message": "Invalid authentication credentials" }

Here’s what I’ve verified so far:
SUPABASE_ANON_KEY is correctly defined in .env

The key is correctly injected into the supabase-kong container (docker exec env | grep SUPABASE_ANON_KEY)

kong.yml shows the correct key under:
keyauth_credentials:
- key: $SUPABASE_ANON_KEY

I rebuilt everything with:
docker compose down -v
docker compose up -d --build

Direct curl test still fails:
curl https://supabase.mydomain.fr/rest/v1/ \
-H "apikey: MY_ANON_KEY"

→ returns "Invalid authentication credentials"

So Kong receives the apikey header but rejects it.

Is there something else required for Kong declarative config to correctly register the key-auth credentials in self-hosted mode?

(i tried to use a supabase project on cloud and it works, so i believe this is due to a bad configuration of my selfhosted supabase)

Thanks
