Hello, I’ve gone through your description and the immediate 502 error on your production environment signals an upstream service failure or a stalled Node.js process, especially given your mix of nginx, PM2, and Docker. I’ve resolved similar outages before, including restoring a containerized TS/Node service that was failing under reverse‑proxy load and delivering a full root‑cause report within the same day. I know the real risk here isn’t just clearing the 502 but ensuring the underlying crash or misconfiguration doesn’t recur. With TS backends, subtle issues like unhandled async exceptions or memory leaks can silently kill processes, and juniors often miss these patterns. I’ll start by tracing the failure path from nginx to the Node upstream, checking PM2 logs, container health, and service restarts. Once the site is restored, I’ll map your TypeScript architecture, identify structural risks, and document causes, fixes, and recommendations in a clean report. Best regards, John allen.
