WebSocket Drops Connection with No Automatic Reconnection
Your application's WebSocket connection drops after network interruptions, server restarts, or idle timeouts, and never attempts to reconnect. Users see stale data, missing notifications, and a broken real-time experience until they manually refresh the page.
WebSocket connections are inherently fragile. Mobile networks switch between WiFi and cellular, laptops sleep and wake, load balancers have idle timeouts, and servers restart during deployments. Without automatic reconnection, every one of these common events breaks your app for affected users.
The issue is worst on mobile devices where network conditions change frequently. Users may not realize their connection is dead until they wonder why they haven't received any updates in minutes.
Error Messages You Might See
WebSocket connection closed unexpectedly
WebSocket is already in CLOSING or CLOSED state
Error: Connection timeout
failed: Connection reset by peer
WebSocket handshake: 502 Bad Gateway
Common Causes
- No reconnection logic — The code creates a WebSocket connection but has no 'onclose' or 'onerror' handler to trigger reconnection
- Single connection attempt — The connection is established once on page load and never retried
- Missing heartbeat/ping — No keepalive mechanism to detect dead connections before the OS TCP timeout (which can be minutes)
- Server-side idle timeout — Load balancers or proxies (Nginx, Cloudflare) close idle WebSocket connections after 60-120 seconds
- No state recovery after reconnect — Even when reconnection works, missed messages during the disconnection are never recovered
How to Fix It
- Implement exponential backoff reconnection — On disconnect, retry at 1s, 2s, 4s, 8s, 16s intervals up to a maximum of 30s. Add jitter to prevent thundering herd
- Add client-side heartbeat — Send a ping message every 30 seconds and expect a pong within 5 seconds. If no pong, treat the connection as dead and reconnect
- Use a WebSocket library with built-in reconnection — Libraries like reconnecting-websocket, Socket.IO, or Ably handle reconnection automatically
- Implement message recovery — Track the last received message ID. On reconnect, request missed messages from the server since that ID
- Show connection status to users — Display a banner when disconnected so users know data may be stale

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

Hey I'm Sage! Im a Boston area software engineer who grew up in South Florida. Ive worked at a ton of cool places like a telehealth kidney care startup that took part in a billion dollar merger (Cricket health/Interwell health), a boutique design agency where I got to work on a ton of exciting startups including a photography education app, a collegiate Esports league and more (Philosophie), a data analytics as a service startup in Cambridge (MA) as well as at Phillips and MIT Lincoln Lab where I designed and developed novel network security visualizations and analytics. I've been writing code and furiously devoted to using computers to make people’s lives easier for about 17 years. My degree is in making computers make pretty lights and sounds. Outside of work I love hip hop, the Celtics, professional wrestling, magic the gathering, photography, drumming, and guitars (both making and playing them)

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
Get HelpFrequently Asked Questions
Why does my WebSocket disconnect after 60 seconds of inactivity?
Most load balancers and reverse proxies (Nginx, Cloudflare, AWS ALB) have a default idle timeout of 60-120 seconds. Send periodic ping messages (every 30s) to keep the connection alive, or increase the proxy timeout.
Should I use WebSocket or Server-Sent Events?
Use WebSocket for bidirectional communication (chat, collaborative editing). Use SSE for server-to-client only (notifications, live updates). SSE has built-in reconnection and is simpler to implement.
