Was faced an error 413 request entity too large on NGINX while configuration for my application, finally found the solution to fix this issue, you simply need to add client_max_body_size to BOTH the HTTP server block and the HTTPS server block

When run the phpMyAdmin tool in a Docker container and configured in the NGINX virtual host with the reverse proxy received the warning appearing at the phpMyAdmin login screen.

Shows a warning Message when checked the NGINX configuration using the command nginx -t, nginx warn the ssl directive is deprecated use the listen ssl,

If you have enabled an option accept_mutex is set to on, worker processes will accept new connections by turn. Otherwise, all worker processes will be notified about new connections.

If would like to configure redirecting a domain1.com to domain2.com in NGINX server, there are two major good rewrite rules here,

HTTP2 protocol is replacement of HTTP1.1 protocol, Its based on SPDY, HTTP2 is more efficient, more secure and faster data transfer in applications.

If you are occurred an error when you configured reverse proxy to another web server, need to increasing value of proxy read timeout in NGINX configuration file.
