Node.js ECONNRESET: Where It Comes From and What to Do

Symptom

Random "read ECONNRESET" crashes or 500s under load.

The remote end closed the TCP connection mid-flight (idle timeout, restart, LB drain).

1. Handle it on the socket, not the processreq.on('error', e => { if (e.code === 'ECONNRESET') return retry(); throw e })

2. Set keep-alive on outbound agentsnew https.Agent({ keepAlive: true, keepAliveMsecs: 30000 })

3. Add retries with jitter for idempotent callsretryOn(error => error.code === "ECONNRESET")

Treat any upstream as a service that restarts: timeouts + retries + circuit breaker.
