TLDR; I am trying to set up a reverse proxy with NPM but no matter what I do the only thing I get is the welcome to nginx webpage.

I have a haos vm as well as a jellyfin server running on my windows 11 machine, with docker desktop running NPM. I have a cloudflare domain pointing at my IP and a CNAME for a jellyfin subdomain. I want to be able to put in jellyfin.mydomain.com and it pull up my jellyfin server and same for home assistant.

I have a proxy host in NPM for each of those subdomains pointing at the IP addresses and ports of each service respectively and all I get is the welcome to nginx page, if I delete the proxy hosts I get the cloudflare could not resolve dns error like it can't find the site which I expect but when I re add the host it goes back to the welcome page even if I go into settings and change from congratulations to 404. I'm not sure what I'm doing wrong or if I'm just screwed on windows. tya
