Unsolved 4xx error help

[lgeprimeplumbing]

Good morning. My site says I have over 300 pages with 4xx errors. When I go in to check they are either labeled with a code 406 or 409. My page is set without the www before the url but I see that it is considered a redirect. Can this be the cause?

Thanks in advance.

The HTTP status codes 406 and 409 indicate different types of errors, and they can have various causes. Let's explore each of these codes and the possible reasons for the errors:

HTTP 406 - Not Acceptable:

The HTTP 406 status code typically occurs when the server cannot fulfill the request because the client's requested response format is not available or not acceptable.
This error can occur if the client (such as a web browser) sends a request with specific headers indicating the desired response format (e.g., JSON, XML), but the server cannot provide that format.
To resolve this issue, you may need to review the request headers being sent by the client and ensure that your server is configured to handle the requested response formats. Alternatively, you can modify the client-side code or configuration to handle the available response formats.
HTTP 409 - Conflict:

The HTTP 409 status code indicates that there is a conflict with the current state of the target resource, often due to a conflicting modification or versioning issue.
This error can occur if there are conflicts between the client's request and the server's current state, such as attempting to update a resource that has been modified since the client last accessed it.
To resolve this issue, you may need to investigate the specific requests that trigger the 409 error and identify any conflicts or synchronization problems. Review your application logic or server-side code to ensure proper handling of concurrent updates and avoid conflicts.
Regarding the use of the "www" prefix, it typically shouldn't cause a 406 or 409 error by itself. However, if your website is configured to redirect from one URL structure to another (e.g., from "example.com" to "www.example.com" or vice versa), improper redirections or misconfigurations could potentially result in such errors. Ensure that your URL redirections are set up correctly to avoid any conflicts.

To address the issue of the reported 4xx errors on your site, it's important to investigate the specific URLs and requests triggering these errors. Check your server logs, review the configuration of your web server or application, and analyze the requests to identify any patterns or common causes for the errors. Fixing any configuration or code issues related to the requests should help resolve the reported errors.

@lgeprimeplumbing It's unlikely that the absence of 'www' is causing the 4xx errors since that's standard practice. However, these errors could arise from different issues. Code 406 happens when the server can't meet the request's "Accept" headers, whereas 409 indicates a conflict, like simultaneous updates. A thorough website audit, including your content negotiation strategy and version control system, can help pinpoint and fix the problem.
