406 Not Acceptable Magento | Troubleshooting Tips

According to our experts, the 406 Not Acceptable error is an HTTP status code that occurs to let us know that the web server cannot generate a response that matches the specified content types in the client’s request.

Interestingly, this error occurs in Magento due to several reasons:

• Missing or incorrect headers:

  The client’s request may be missing the “Accept” header. Alternatively, the header may contain incorrect or unsupported content types.
• Misconfigured web server:

  The web server may be incorrectly configured to handle the requested content types. Sometimes, it may lack the needed modules or configurations.
• Invalid extensions or modules:

  Third-party extensions or modules in Magento may be interfering with content negotiation.
• Corrupted or incomplete files:

  In case specific files, like template files or static assets, are corrupted or missing, the error will occur.

How to troubleshoot 406 Not Acceptable error in Magento

• First, we must ensure the client’s request includes a valid “Accept” header with the correct content types. Additionally, we can check the request headers with browser developer tools or other HTTP inspection tools.
• Next, we have to check the server configuration to make sure that it is set up to handle content negotiation correctly. We have to ensure that necessary modules or extensions are enabled.
• Then, temporarily disable any third-party extensions in Magento to see if they are behind the issue. If the error disappears, we can try re-enabling the extensions one by one to identify the ones causing the error.
• Now, we have to clear Magento’s cache to make sure that any outdated or corrupted cache files are not affecting the response generation.
• Next, we have to check if any of the files are missing.
• Finally, check if we are using the latest stable version of Magento.
