I have a Docker installation on Ubuntu, using Portainer to manage it. I have an n8n container and a Supabase container running properly and can access both from the internet, but have no success using n8n to connect to Supabase via setting up an n8n account credential. Likely some issue with Docker networking not allowing n8n to reach Supabase, or perhaps I’ve got the host wrong in the n8n account credential.
