I am trying to intercept errors from a Unicorn proxy\_pass and display a  
custom 40x error page that is located on disk. This is what a subscript  
of my config:

proxy\_intercept\_errors on;  
error\_page 400 403 =404 /404.html;  
location /404.html {  
allow all;  
internal;  
}

When I receive a 403 error from NGINX it is passing to the location and  
rendering the 404.html error page in my root. When the upstream returns  
a 400 response NGINX is intercepting it but not rendering the 404.html  
file, instead it returns the generic NGINX 400 error response page.

Thank you in advance!

Update: It seems that all response codes I specify in error\_page are  
intercepted by NGINX but do not pass to the /404.html location to render  
the custom error page.

My solution was to enable recursive\_error\_pages
