How can I handle errors in Nginx reverse proxy?

You can handle errors in Nginx reverse proxy by using the error_page directive to specify custom error pages.

Can you give me an example of how to set that up?

Sure! You can add something like this in your Nginx configuration:

error_page 404 /custom_404.html;
location = /custom_404.html {
    root /usr/share/nginx/html;
    internal;
}

What about handling 502 Bad Gateway errors?

For 502 errors, you can also use the error_page directive. For example:

error_page 502 /custom_502.html;
location = /custom_502.html {
    root /usr/share/nginx/html;
    internal;
}

Is there a way to log these errors?

Yes, you can log errors by configuring the error_log directive in your Nginx configuration file.
