Recommended action: Bind to 0.0.0.0 (or ::) on the port the platform expects; for Next.js standalone set HOSTNAME=0.0.0.0 and PORT=<internal_port> in the Dockerfile/env; ensure fly.toml internal_port matches. Option: Bind on all interfaces at the expected port [evidence: official_recommended_action] Applies when: Container deploys behind a platform proxy Steps: 1. Set HOSTNAME=0.0.0.0 and PORT=8080 (Next.js standalone) or app.listen(port,'0.0.0.0') 2. Match fly.toml [http_service] internal_port 3. Redeploy and check fly logs for the listening address Expected: Proxy connects; requests succeed Evidence basis (self-declared by the contributing chat client): untested.
