Return custom 403 error page with nginx

Question

Im trying to display the error page in /temp/www/error403.html whenever a 403 error occurs.

This should be whenever a user tries to access the site via https (ssl) and it's IP is in the blovkips.conf file, but at the moment it still shows nginx's default error page. I have the same code for my other server (without any blocking) and it works.

Is it blocking the IP from accessing the custom 403 page? If so how do I get it to work?

server  {
    # ssl
    listen               443;
    ssl                  on;
    ssl_certificate      /etc/nginx/ssl/site.in.crt;
    ssl_certificate_key  /etc/nginx/ssl/site.in.key;
    keepalive_timeout    70;

    server_name localhost;


    location / {
            root   /temp/www;
            index  index.html index.htm;
}

# redirect server error pages to the static page
error_page   403  /error403.html;
# location = /error403.html {
#         root   /temp/www;
# }

    # add trailing slash if missing
    if (-f $document_root/$host$uri) {
            rewrite ^(.*[^/])$ $1/ permanent;
    }      

    # list of IPs to block
    include blockips.conf;
}

Edit: Corrected error_page code from 504 to 403 but I still have the same issue

Answer 1

I did heaps of googling before coming here but did some more just now, within 5 minutes I had my answer :P

Seems I'm not the only person to have this issue:

error_page 403 /e403.html;
  location = /e403.html {
  root   html;
  allow all;
}

Seems that I was right in thinking that access to my error page was getting blocked.
