@Demetry,

Instead creating custum error configuration file, I suggest you to add following lines within the http block to set up the custom error page in the mail /etc/nginx/nginx.conf configuration file.

http {
    # ... Other configuration settings ...

    server {
        listen 80;
        server_name your_domain.com;  # Replace with your actual domain name

        # Location block for the custom error page
        location / {
            error_page 404 403 500 503 /error-page.html;
            root /var/www/html;  # Replace with the actual path to your HTML file
            index index.html;
        }

        # ... Other server settings ...
    }
}

After making the changes, restart NGINX to apply the changes:

$ sudo systemctl restart nginx

Should I go with ‘location.main-before’?

I want to set a 404 error page for a static custom website.

Thanks.

My client sends an HTTP header – X-Correlation-Id – and when nginx there is a circumstance when nginx sends a 404, I’d like to include in the 404 page, the X-Correlation-Id HTTP Header, with the same value, so that we can match up nicely.

How do I do that? Thank you!

nginx: [emerg] “internal” directive is not allowed here in /etc/nginx/snippets/custom-error-page.conf:4.

I have tried placing include /etc/nginx/snippets/custom-error-page.conf; at different places in the nginx.conf file and get a different error message.

Thanks
