Nginx – Change error page for 502 Bad Gateway error Nginx not working

502nginx

I have researched online for a means to change the error page when running into a 502 Bad Gateway error. I have tried all the methods given to no avail. I looked in the nginx.conf file and saw that it points to /usr/share/nginx/html/50x.html when dealing with 500 errors. However this page is never shown. Instead it shows

502 Bad Gateway

nginx/1.16.1

What am I missing?

I followed this guide https://blog.adriaan.io/one-nginx-error-page-to-rule-them-all.html

And others, but I am beginning to think that there is another issue altogether that is bypassing my code.

Sample example is below, kindly change paths and names accordingly.

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    error_page 500 502 503 504 /custom_50x.html;
    location = /custom_50x.html {
            root /usr/share/nginx/html;
            internal;
    }}
