Page indexing issues with finding (404) Page and Soft 404

Google informed me that it has detected page indexing issue on my site. Its not able to find my 404 error page. However I do have the page on my site Page 404 | I did some research and one of the solution provided is “check your web server settings to ensure that the server is configured to return a 404 error for missing pages” How do I go about doing that.

This is the exact email i have from google
