Reverse Proxy Nginx Docker Container - docker

Question

I have problems to run multiple proxies and connect a nginx reverse proxy to it.
The image show what I want to archive
What works is when I connect to a proxy directly
# proxy 1
print(requests.get("https://api.ipify.org?format=json", proxies={
"http": "127.0.0.1:9000",
"https": "127.0.0.1:9000"
}).content)
# proxy 2
print(requests.get("https://api.ipify.org?format=json", proxies={
"http": "127.0.0.1:9001",
"https": "127.0.0.1:9001"
}).content)
But it did not work when I use the nginx reverse proxy
# nginx
print(requests.get("https://api.ipify.org?format=json", proxies={
"http": "127.0.0.1:8080",
"https": "127.0.0.1:8080"
}).content)
Response:
requests.exceptions.ProxyError: HTTPSConnectionPool(host='api.ipify.org', port=443): Max retries exceeded with url: /?format=json (Caused by ProxyError('Cannot connect to proxy.', OSError('Tunnel connection failed: 400 Bad Request')))
That's my docker container yml file
docker-compose.yml
version: "2.4"
services:
proxy:
image: qmcgaw/private-internet-access
cap_add:
- NET_ADMIN
restart: always
ports:
- 127.0.0.1:9000-9001:8888/tcp
environment:
- VPNSP=Surfshark
- OPENVPN_USER=${user}
- PASSWORD=${pass}
- HTTPPROXY=ON
scale: 2
nginx:
image: nginx
volumes:
- ./default.conf:/etc/nginx/conf.d/default.conf
ports:
- "8080:80"
and my nginx configuration
default.conf
server {
listen 80;
server_name localhost;
location / {
proxy_pass http://proxy:8888;
}
}
I'd appreciate any advice you can give me.

Actually that's not what I wanted, but it works with twisted instead of nginx. Maybe someone finds a better solution.
docker-compose.yml
version: "2.4"
services:
proxy:
image: qmcgaw/private-internet-access
cap_add:
- NET_ADMIN
restart: always
environment:
- VPNSP=Surfshark
- OPENVPN_USER=${user}
- PASSWORD=${pass}
- HTTPPROXY=ON
scale: 2
twisted:
container_name: twisted
build: .
restart:
always
ports:
- 127.0.0.1:8080:8080/tcp
healthcheck:
test: ["CMD-SHELL", "curl https://google.de --proxy 127.0.0.1:8080"]
interval: 20s
timeout: 10s
retries: 5
