also, yeah, your current nip-05 from rogue.earth has one as well, i guess the domain has one being served.
the reverse proxy i made is nice tho, does go vanity redirects as well as nip-05 serving, and you can also do lots of other neat things, it does letsencrypt certs automatically for you, you can set your own custom certs and they have precedence so you can set a custom cert with a wildcard and all subdomains from a wildcard will use it (i forget exactly how i did that, but it's there anyway)
