WebSocket Connection Fails - Real-time Features Not Working
WebSocket connections fail to establish. Real-time features don't work. Users don't receive live updates.
Connection hangs or connects then disconnects immediately.
Error Messages You Might See
WebSocket connection failed
Error: WebSocket is closed
ERROR: connection reset by peer
WebSocket: error during handshake
Common Causes
- Server doesn't support WebSocket upgrades
- Proxy/firewall blocking WebSocket (wss protocol)
- Incorrect WebSocket URL (ws vs wss)
- CORS/origin headers missing for WebSocket
- WebSocket message parsing error
How to Fix It
Use wss:// (secure WebSocket) in production, ws:// for local dev
Verify server supports WebSocket: check framework docs (Next.js uses socket.io or similar)
Add origin check: allow your domain in WebSocket upgrade handler
Handle reconnection: exponential backoff when connection drops
Test locally: use browser DevTools Network tab to monitor WebSocket frames
Real developers can help you.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

Get HelpFrequently Asked Questions
Should I use ws or wss?
Always wss (secure). ws only for local development
How do I implement reconnect?
On close, wait 1s then reconnect. If fails, wait 2s, 4s, etc. Max 5-10 retries
What's socket.io vs raw WebSocket?
socket.io adds features (rooms, acknowledgments, auto-reconnect). Use socket.io unless you need raw protocol
