Not Found on Path

[TobiTenno]

[server]
port = 8099
hostname = "https://something.domain.tld:443/podcasts/"
path = "podcasts"

(also attempted with bind_address = "*")

docker.compose.yml:

services:
  podsync:
     container_name: podsync
     image: mxpv/podsync:latest
     restart: always
     ports:
       - 8099:8099
     volumes:
       - ./data:/app/data/
       - ./config.toml:/app/config.toml

nginx:

    location /podcasts/ {
        proxy_pass              http://localhost:8099/podcasts;
        proxy_set_header        Host            $http_host;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header        X-Scheme        $scheme;
        proxy_set_header        X-Script-Name   podcasts;
    }

when I attempt to visit https://something.domain.tld/podcasts/ID1.xml, I end up with 404 page not found.

(i've tested the config for downloading and seeing a specific ID locally and it works, that part i'm not concerned about)

this is different compared to if i'm hitting wiht the server down or inaccessible, but I can't find where i'm missing something or misconfigured.
