Hello,
We apologize for the issue you are facing with your sitemap not being read by Google Search Console. Here are some steps you can follow to troubleshoot and potentially resolve the "Couldn’t fetch" error:
1. Validate Your Sitemap
First, ensure that your sitemap is correctly configured. You can use the Validate XML Sitemap tool. Enter your sitemap URL and click VALIDATE SITEMAP. If your sitemap is correctly configured, you should 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 URL should look like this:
`https://rankmath.com/kb/how-to-change-canonical-url/
3. Ensure Your Posts Are Set to Index
Check if your posts are set to index. Go to Rank Math SEO → Titles & Meta and ensure the Index checkbox is enabled in the Robots Meta settings.

4. Flush the Cache
If your sitemap appears outdated, you may need to flush the sitemap cache. Navigate 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 to ensure the current settings are applied.

5. Add the Correct Sitemap to Google Search Console
Make sure you have added the correct sitemap URL in Google Search Console. Navigate to Indexing → Sitemaps, paste your sitemap URL, and click SUBMIT. Ensure there are no spaces in the URL.

If you continue to experience issues after following these steps, please reply to this ticket, and a human agent from our support team will assist you further. Thank you for raising this concern!
