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

I build and fix web apps across Next.js, Node.js, and DBs.
Comfortable jumping into messy code, broken APIs, and mysterious bugs.
If your project works in theory but not in reality, I help close that gap.
Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

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
