ROOT CAUSE FIX: All server-side Supabase clients (server-client, middleware-client, server-admin-client) now use SUPABASE_INTERNAL_URL (http://supabase-kong:8000) when available, with cookieOptions.name set to match the external URL's cookie key (e.g. sb-myeasycms-auth-token). This gives us: - Reliable Docker-internal networking (no hairpin NAT through Traefik) - Correct session cookie matching between browser and server - No more 500 errors on SSR pages that query Supabase Reverted per-page try/catch workarounds since root cause is now fixed.
