Hello,
We apologize for the issue you are facing with your sitemap. Since you are using an NGINX server, it’s important to ensure that the necessary rewrite rules are added to your NGINX configuration file to allow Rank Math to generate the sitemap correctly.
To check if your sitemap is working, please visit this link. If it loads correctly, then Rank Math is generating the sitemap, but if you encounter issues, you may need to add the following rewrite rules to your NGINX configuration:
# START Nginx Rewrites for Rank Math Sitemaps
rewrite ^/sitemap_index.xml$ /index.php?sitemap=1 last;
rewrite ^/([^/]+?)-sitemap([0-9]+)?.xml$ /index.php?sitemap=$1&sitemap_n=$2 last;
rewrite ^/([a-z]+)?-sitemap.xsl$ /index.php?xsl=$1 last;
# END Nginx Rewrites for Rank Math Sitemaps
After adding these rules, make sure to flush your sitemap settings by going to Rank Math SEO → Sitemap Settings in your WordPress admin area and making any minor changes before saving.
If you’re unsure how to proceed with these changes, we recommend reaching out to your hosting provider for assistance. Thank you for raising this concern, and if you have any further questions or need additional help, please reply to this ticket, and a human agent will assist you further!

I really can’t tell for sure whether my sitemap is working properly. A bunch of sitemap checkers can’t find it. Still need human help
Hello,
Thank you for your query and we are so sorry about the trouble this must have caused.
Your sitemap is loading fine when you visit it in the browser. However, crawlers are currently greeted with a blockage as you can see from the screenshots below:


This is something you need to check with your hosting provider and make sure your sitemap is reachable to search engine crawlers.
Let us know how that goes. Looking forward to helping you.
