Connection refused?

Im setting up pterodactyl + nginx proxy manager but im running into some issues.

i setup a proxy host

it gives me a ERR_SSL_UNRECOGNIZED_NAME_ALERT error. so i added a ssl cert! it gave me a 502 bad gateway.
but if i do curl 0.0.0.0:8000 i can see the html, also if i do serverIP:8000 i can see it too.
i went to the logs and i see

2023/10/19 02:07:57 [error] 400#400: *544 connect() failed (111: Connection refused) while connecting to upstream, client: MY IP, server: panel.domain.tld, request: "GET /favicon.ico HTTP/2.0", upstream: "http://0.0.0.0:8000/favicon.ico", host: "panel.domain.tld", referrer: "https://panel.domain.tld/"
