Hello,
We apologize for the issue you are facing with your sitemap. The "Couldn’t fetch" error in Google Search Console can be caused by several factors. Here are some steps you can take to troubleshoot and potentially 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, it should return a success message.

2. Check Sitemap Location
Make sure your sitemap is located in the root folder of your WordPress installation. The correct URL format should be:
https://img.youtube.com/vi/-QZro6QysCA/maxresdefault.jpg
3. Ensure Posts Are Set to Index
If all your posts are set to noindex, your sitemap will be empty. To check this, go to Rank Math SEO → Titles & Meta and ensure the Index checkbox is enabled for your posts.

4. Flush Permalinks
If you encounter a 404 error, try flushing permalinks by going to the Permalinks settings in your WordPress dashboard and clicking Save Changes without making any changes.
5. Check for Plugin Conflicts
Sometimes, other plugins can conflict with Rank Math. You can use the Health Check plugin to identify any conflicts.
6. Check robots.txt File
Ensure that your sitemap URL is not blocked by the robots.txt file. You can check this in Rank Math SEO → General Settings → robots.txt.
If you continue to experience issues after trying these steps, please reply to this ticket with your site URL so we can assist you further. A human agent from our support team will take over and provide more specific guidance.
