In this tutorial, we explain what a 424 error code is and how to resolve it. The HTTP 424 status code belongs to the HTTP 4xx family. It indicates that the method used in the previous request failed. With the HTTP 424 status code sequence, the requests are crucial. In the following paragraphs, we will provide a more detailed explanation of HTTP 424. This covers the causes and the primary differences between HTTP 424 and other status codes.
In the final and most crucial paragraph, we will discuss potential fixes for the HTTP 424 Error. Let’s get started!

What is the HTTP 424 Error status code?
The HTTP 424 is a failed dependency status code. It indicates that the request on a web resource can not be executed. This is typically because it was dependent on a previous unsuccessful action. The HTTP 424 status code, also known as the HTTP 424 error code, is a part of the WebDAV (Web Distributed Authoring and Versioning) protocol, which extends the HTTP protocol. The WebDAV protocol allows collaborative management and file editing on the web server. Moreover, the operations in the WebDAV protocol are interdependent, meaning the success of one action relies on the successful completion of the previous one. In other words, the requested action can not be completed until the requested dependency is completed or resolved. If this is not fulfilled, we will receive the HTTP 424 error in the browser. Let’s proceed with the causes for the HTTP 424 status code.
The Causes of the HTTP 424 Error Code
In this section, we will discuss the potential causes of the HTTP 424 status code.
Resource Locking is one of the possible causes of dependency failure and the HTTP 424 status code, as the user attempts to modify a currently locked resource.
Missing Prerequisite: This occurs when a request relies on another request that has not been fulfilled. For instance, in a WebDAV PROPPATCH request, if an update to one property fails, the entire request might result in a 424 status code.
Sequential Failure: The failure of the preceding request prevents the subsequent requests from being executed successfully.
Incorrect or Incomplete Configurations: The action may fail if there is a system or service misconfiguration.
Server-side errors are also a cause for this code to appear. There may be internal server issues, database connectivity problems, or application-related errors, such as bugs or faulty code.
HTTP 424 vs other HTTP 4xx Errors
The HTTP 4xx status code indicates a client error, where the sent request is somehow invalid. Therefore, preventing the server from fulfilling it and returning a valid response. The HTTP 424 status code, compared to other HTTP 4xx status codes, is unique, and the HTTP 424 failed dependency status code is considered a specific type of client error that distinguishes itself from other status codes. Unlike some general client errors, such as Bad Request (HTTP 400) or Not Found (404 Error), the HTTP 424 specifically indicates a dependency failure. The request is syntactically correct, but it can not be executed because of a prior unsuccessful action. Other HTTP 4xx status codes are standard across web applications, while HTTP 424 is more prevalent in environments that utilize protocols such as WebDAV, where operations have explicit dependencies.
How to fix the HTTP 424 Error Code?
Finally, we have reached the last heading of the tutorial, which is about resolving the HTTP 424 Error code. Here are some possible fixes:
Review server configuration: Reviewing a web server configuration is always a good idea when an HTTP 4xx status code appears.
Web Application code checking is also a good idea for fixing the HTTP 424 error. There may be a bug or invalid code in the forms that could cause this error to appear.
Handle resource locking: Implementing a retry mechanism with wait timeouts or other workflows may fix the HTTP 424 error.
Check the Syntax and methods to verify that the syntax of the request causing the error is correct, and appropriate HTTP methods and headers are used.
Verify the credentials to ensure that the authentication tokens and API keys are valid, as invalid authentication can cause dependency failures.
Resolve Sequential Issues: Verify that all preceding requests have been completed successfully to enable subsequent requests.
Verify network connectivity to ensure that there are no network issues, as these may prevent the application and the dependent device from communicating properly.
Conclusion
The HTTP 424 or Failed Dependency Error can negatively impact a website’s SEO, indicating a poor user experience and reduced crawlability. If Google detects persistent HTTP 424 Errors, it will reduce the crawling frequency on specific pages of the website. Over time, if the HTTP 422 Error is not resolved, Google may remove the website from its search engine index, which is detrimental to both customer experience and traffic. Fixing the HTTP 424 error is inevitable.
