Hi,
I'm using aaPanel and I installed Nginx. When I tried to add sitemap on google search, I got Noindex detected in "X-Robots-Tag" http header this error. I installed Rankmath plugin and i disable for testing header tag, and i still saw same error.
I searched add_header code in Nginx conf but i couldnt find anything. And i added add_header X-Robots-Tag "all"; for allowing search engines, it doesnt work. I really got annoyed from that and i couldnt find solving. When i checked my http header, i saw that

my website: https://dailycourse.top sitemap: https://dailycourse.top/sitemap_index.xml robots.txt https://dailycourse.top/robots.txt
How can i remove x-robots-tag noindex?
PS: I tried so many things.
Google doesnt index my web site bcs of that
