What is 500 Internal Server Error in NGINX ??? ...
NGINX gives 500 Internal Server Error when there is a server-side error that prevents NGINX from returning a proper response. It can be due to many different reasons such as faulty script, missing files referenced by code, inadequate file permissions, etc. NGINX is typically used as a reverse proxy server, so the most common reason for 500 Internal server is an error in one of its web servers like Apache that has encountered an issue and returned a 500 error response to NGINX, which is then returned to client browsers. There are various ways to fix internal server error in NGINX.
