What is a 404 Error?

A 404 error, also known as a "Not Found" error, is a common HTTP status code that occurs when a user attempts to access a webpage or resource that does not exist on the server. This error is typically displayed when the server is unable to find the requested resource, either because it has been deleted, moved, or never existed in the first place.

Causes of 404 Errors

There are several reasons why a 404 error may occur, including:

  • Incorrect URL: If the URL is misspelled or incorrect, the server will return a 404 error.
  • Deleted or moved resources: If a webpage or resource has been deleted or moved, the server will return a 404 error.
  • Server configuration issues: Issues with the server's configuration, such as incorrect file paths or permissions, can cause 404 errors.
  • Browser cache issues: In some cases, browser cache issues can cause 404 errors.

The Issue with Shortened Keys

In your case, the issue seems to be related to the key being shortened when input. This can cause a 404 error because the server is unable to find the requested resource. There are several reasons why this might be happening, including:

  • Character encoding issues: If the key is being input using a character encoding that is not compatible with the server, it may be shortened or truncated.
  • URL length limitations: Some servers have limitations on the length of URLs, which can cause shortened keys to be truncated.
  • Browser or client-side issues: Issues with the browser or client-side software can cause shortened keys to be input.

Why Shortened Keys Cause 404 Errors

When a key is shortened, it can cause a 404 error because the server is unable to find the requested resource. This is because the shortened key may not match the expected key format, or it may be truncated or missing critical information.
