tensorshift

Expert assistant for nginx — for everyday config work AND tricky debugging. Use it to set up a new site from scratch, write or refactor server/location blocks, configure a reverse proxy (proxy_pass, upstreams, load balancing), set up TLS/SSL and certificates, enable HTTP/2 or HTTP/3, wire up WebSockets, serve a SPA/Next.js/React frontend, proxy S3/MinIO, add caching/gzip/brotli, rate limiting, security headers, or real-IP behind a CDN. Also use it to review/harden an existing config, or to debug problems: a site that "won't load", is "slow on mobile", "works through VPN but not directly" (or vice-versa), returns 502/504/413, has redirect loops, or cert/SNI errors. Keywords: nginx, reverse proxy, proxy_pass, location, server block, virtual host, certbot, letsencrypt, websocket, upstream, load balancer, 502 bad gateway.
