I'm using Rank Math to generate sitemap_index.xml. But sometimes the sitemap doesn't accessible and the URL shows a 404 error. As per rank math to use sitemap on the Nginx server we have to add the below code in the configuration file. So I don't know where the file is located and in which file I have to insert that code?
`# 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;

END Nginx Rewrites for Rank Math Sitemaps`

    It says 'you may need to add the following code...' I'm using Rank Math myself and it doesn't require any extra settings/code for sitemap to work correctly on Nginx.

      Hi my website had the same issue with the sitemap when using rank math.
      I tried various solutions just as you are doing and nothing helped me.

      So I just disabled the sitemap of rankmath and installed another 3rd party xml sitemap plugin.
      Now everything is working fine.
      Now i dont get 404 pages and wrong redirects.
