To display a custom error page for 400 errors on an Nginx server, you can try and use a custom error page. This could be an HTML page with the content you want to show to users when they hit a 400 error.
Once you have created the custom error page, you will need to edit your Nginx configuration file. This is usually located at /etc/nginx/nginx.conf
or /etc/nginx/sites-available/default
or a similar location, depending on your server setup.
You would then add an error_page directive inside the server block for your site, pointing to the location of your custom error page. It would look something like this:
server {
listen 80 default_server;
server_name example.com;
# Rest of your configuration...
error_page 400 /path/to/your/error400.html;
location = /path/to/your/error400.html {
internal;
}
}
In the above configuration, replace /path/to/your/error400.html
with the actual path to your custom error page. You might need to restart your Nginix service to make these changes work.
