Hello,
Thank you for contacting Rank Math support, and sorry for the unexpected delays and any inconvenience that might have been caused due to that.
The sitemap path you shared is incorrect but it seems the same issue is happening in the correct path: https://thetexaszone.com/sitemap_index.xml
Please add the rewrite rules to your Nginx server to address this issue: https://rankmath.com/kb/xml-sitemaps-nginx/#fix-sitemap-issues-on-nginx-server
After that, follow the steps below:
1. Flush the Sitemap cache by following this video screencast:

2. Exclude the Sitemap files of the Rank Math plugin in your caching plugin. The cache could be via a plugin or from the server. For plugins or Cloudflare, please follow this article:
https://rankmath.com/kb/exclude-sitemaps-from-caching/
3. Apply the following filter code to your site.
add_filter( 'rank_math/sitemap/enable_caching', '__return_false');
Here’s how you can add a filter to your WordPress site:https://rankmath.com/kb/wordpress-hooks-actions-filters/
Let us know how that goes.
