Hello,
We apologize for the issue you are facing with Google Search Console not fetching your Rank Math sitemap. It can be frustrating when your latest blogs are not getting indexed. Here are some steps you can follow to troubleshoot and resolve the "Couldn’t fetch" error:
1. Validate Your Sitemap
Make sure your sitemap is correctly configured. You can validate it using the Validate XML Sitemap tool. If there are no issues detected, you should see a success message.

2. Ensure the Sitemap is Located in the Root Folder
Your sitemap should be located in the root folder of your WordPress installation. The URL should look like this:
https://yourdomainname.com/sitemap_index.xml
3. Check Index Settings for Posts
Ensure that your posts are set to index. Go to Rank Math SEO → Titles & Meta and make sure the Index checkbox is enabled for your posts.

4. Flush the Cache
If your sitemap appears outdated, you may need to flush the cache. Increase the value of Links Per Sitemap by one in Rank Math SEO → Sitemap Settings, then save changes.

5. Exclude the Sitemap From Caching
Make sure your sitemap is not being cached. You can refer to this article on ensuring that your sitemaps are excluded from caching.
6. Add the Correct Sitemap URL to Google Search Console
Finally, ensure you have added the correct sitemap URL in Google Search Console. You can do this by navigating to Indexing → Sitemaps and submitting your sitemap URL again.
If you have followed these steps and are still experiencing issues, please reply to this ticket, and a human agent from the Rank Math Support team will assist you further.
Thank you for raising this concern, and we hope these steps help resolve the issue!

Hello,
Please note that each time Google uses a sitemap to find a URL, the count of the Discovered URLs increases by one. Sitemaps is only one of the few methods Google uses to discover your URLs, so it is fine for your articles to be referred to by other URLs on your site.
Also, when the count of the Discovered URLs is zero or does not match your actual sitemap in your Google Search Console, it means Google didn’t use the sitemap to find the URLs.
Here’s a link for more information:

You should check your Google Search Console > Indexing > Pages section to determine any issues reported on your URLs that may have prevented your site from being indexed:
