What does HTTP 404 mean?

The HTTP 404, 404 Not Found, 404, 404 Error, Page Not Found or File Not Found error message is a Hypertext Transfer Protocol standard response code, in computer network communications, to indicate that the browser was able to communicate with a given server, but the server could not find what was requested.

The Default 404 error pages are not good looking and don't have any type of navigations

Following are some methods you can use to auto-redirect to a custom error page.

• Website Running on Apache webserver

1. Create a custom webpage for 404 error and name it 404.html

2. Create a file name.htaccess

File content: ErrorDocument {error_code} {custom file path}

ErrorDocument 404 /404.html

OR

ErrorDocument 404 https://yourwebsite.com/404.html

Now the site will redirect to 404.html whenever the user gets a 404 HTTP response or browse the wrong URL path on your website.

Here are some hosting services that run on Apache webserver

• Website Hosted on Vercel.com

1. Create a custom webpage for 404 error and name it 404.html

2. Create a file namevercel.json

File content:
