Fix 502 Bad Gateway in Nginx
A 502 Bad Gateway means Nginx could not get a valid answer from PHP-FPM or your app. Read the error log, then check the backend service, socket path, permissions and ports.
Load balance backends with Nginx upstream
Spread traffic across several app instances or servers with an Nginx upstream block, choose round robin, least_conn or ip_hash, and add passive health checks and keepalive.
