Hello,
We apologize for the issue you are facing with your sitemap not updating and the “Couldn’t fetch” error in Google Search Console. Here are some steps you can follow to troubleshoot and resolve the issue:
1. Validate Your Sitemap
First, ensure that your sitemap is correctly configured. You can validate your sitemap using the Validate XML Sitemap tool. Enter your sitemap URL and click VALIDATE SITEMAP. If there are no issues detected, you will see a success message.

2. Ensure the Sitemap is Located in the Root Folder
Make sure your sitemap is located in the root folder of your WordPress installation. The correct URL should look like this:
`https://rankmath.com/wp-content/uploads/2022/11/status-codes-scaled.jpg
3. Check Post Indexing Settings
Ensure that your posts are set to index. Go to Rank Math SEO → Titles & Meta and check the Robots Meta settings. Make sure the Index checkbox is enabled for your posts.

4. Flush the Cache Again
If you haven’t already, try flushing the sitemap cache again by navigating to Rank Math SEO → Sitemap Settings. Increase the value of Links Per Sitemap by one and save your settings. Then, go to Settings → Permalinks and click Save Changes again.

5. Exclude the Sitemap From Caching
Make sure your sitemap is excluded from caching. You can refer to this knowledgebase article on ensuring that your sitemaps are excluded from caching.
6. Add the Correct Sitemap to Google Search Console
In Google Search Console, navigate to Indexing → Sitemaps and ensure you have added the correct sitemap URL. If you still encounter issues, try adding a forward slash before the sitemap URL and click SUBMIT.
If after following these steps the issue persists, we recommend replying to this ticket with any additional details or errors you may be encountering, and a human agent from our support team will assist you further.
Thank you for raising this concern, and we hope these steps help resolve your issue!
