Both services are in EU West, same project, same environment (production). postgres.railway.internal:5432 is completely unreachable from the app container.

WhatI'vetried:

  - pg_isready -h postgres.railway.internal -p 5432 → no response

  - Added retry loop (10 attempts, 3s apart) — all fail with connection timeout

  - Redeploying both services

  - Verified both services are in EU West
