I want to add my forum's sitemap to Google Console. I tried inserting "sitemap.xml" in the blank space. I also tried inserting "/sitemap.xml" and "/sitemap.xml/" because this was a suggested fix in other topics here and elsewhere online. Each time I get an error message: "Couldn't fetch Sitemap". I just can't understand what the issue is and how to fix it.
My forum is at https://bgmagic.bulgarianforum.net/.
