nginx Configuration & Troubleshooting

← Web Infrastructure

nginx as web server, reverse proxy, load balancer or API gateway. 502 errors, TLS issues, performance problems. I debug and fix it.

Typical problems I solve

502

502 Bad Gateway errors, upstream timeout, backend unreachable

TLS

SSL certificate issues, mixed content, HTTPS redirect loops

Proxy

Reverse proxy headers wrong, websockets not working

Perf

Site slow, no caching, gzip not active

Config

Configuration syntax errors, server blocks conflicting

Specific

This is what I have experience with and can help you with.

  • nginx configuration & virtual hosts
  • Reverse proxy setup (upstream, headers, websockets)
  • TLS/SSL configuration & Let's Encrypt automation
  • 502/504 error debugging & upstream tuning
  • Performance optimization (caching, gzip, buffers)
  • Rate limiting & security headers
