Hello,
We apologize for the issue you are facing with indexing your site and the "Couldn’t fetch" error for your sitemap. Here are some steps you can take to troubleshoot and potentially resolve this issue:
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/wp-content/uploads/2021/05/Save-Changes.jpg
3. Ensure Your 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 in the Robots Meta settings.

4. Rename the Sitemap File
If the above steps do not resolve the issue, consider renaming your sitemap file. In Google Search Console, navigate to Indexing → Sitemaps, and add a new sitemap using the following URL:
`https://rankmath.com/wp-content/uploads/2021/05/Save-Changes.jpg

5. Use Instant Indexing Feature
If you want to expedite the indexing process, you can enable Rank Math’s Instant Indexing feature. To do this, go to WordPress Dashboard → Rank Math SEO and enable the Instant Indexing module.

After enabling it, you can submit individual posts for indexing by hovering over the post and selecting Instant Indexing: Submit Page.

If you continue to experience issues after trying these steps, please reply to this ticket with any additional details or errors you encounter, and a human agent from our support team will assist you further. Thank you for raising this concern!

all i did but yet not solve this issue some pages and sitemap live but some are not indexing issue
there is another proble with other indexing platform – The inspected URL is known to Bing but has some issues which are preventing indexation. We recommend you to follow Bing Webmaster Guidelines to increase your chances of indexation.
Hello,
Please share the affected URL so we can check it as well.
Meanwhile, if a URL is on Google, there is technically no reason for it to not be included in Bing or other search engines, unless they have some reason to not index a page like DMCA, copyright content, nulled content, copied content, etc. which you can check in Webmaster Guidelines set by Bing.
Also, you should run the affected URL/s using the URL inspection tool of your GSC account to know their status.
Looking forward to helping you.
