Kubernetes qBitTorrentWebUI showing only on path '/' - nginx

Question

I am trying to host a qBitTorrent server with Kubernetes. I have composed a YAML for the https://hub.docker.com/r/linuxserver/qbittorrent docker container.
The problem is that it is accessible only from path /. As soon as I move it to /torrent it does not find it anymore: 404 Not Found.
Steps to replicate:
apply following yamls
helm install nginx ingress-nginx/ingress-nginx
go to service_ip:8080, settings, WebUI, uncheck "Enable Host header validation"
go to localhost:nginx_port/torrent
Result:
page not loading
Expected Result:
qBitTorrent WebUi appears and works
What I tried:
adding nginx.ingress.kubernetes.io/rewrite-target: / to annotations
server.yaml:
apiVersion: apps/v1
kind: Deployment
metadata:
name: torrent-deployment
labels:
app: torrent
spec:
replicas: 1
selector:
matchLabels:
pod-label: torrent-pod

Thanks to #matt_j I have found a workaround. I wrote and YAML for nginx myself and added the configurations from the post mentioned by matt ( https://github.com/qbittorrent/qBittorrent/wiki/NGINX-Reverse-Proxy-for-Web-UI ) and it worked.
These are the YAMLs I came up with:
server.yaml:
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx
labels:
app: nginx
namespace: nginx
spec:
selector:
matchLabels:
pod-label: nginx
template:
metadata:
labels:
pod-label: nginx
spec:
containers:
- name: nginx
image: nginx:latest
volumeMounts:
- name: nginx-conf
mountPath: /etc/nginx/
volumes:
- name: nginx-conf
configMap:
name: nginx-conf
items:
- key: nginx.conf
path: nginx.conf
replicas: 1
