connection refused when trying to execute a python script in nginx

I have the following Dockerfile:

FROM nginx
RUN apt-get update 
RUN apt-get install python3 python3-pip fcgiwrap -y

the docker-compose.yml:

version: '3.3'
services:

    nginx:
        build: ./data-nginx/.
        container_name: nginx
        restart: always
        ports:
            - "80:80"
            - "443:443"
        networks:
            - webserver
        volumes:
            - ./data-nginx/conf.d/:/etc/nginx/conf.d/
            - ./data-nginx/fastcgi.conf:/etc/nginx/fastcgi.conf
            - ./data-nginx/proxy.conf:/etc/nginx/proxy.conf
            - ./data-nginx/mime.types:/etc/nginx/mime.types
            - ./data-nginx/fcgiwrap.conf:/etc/nginx/fcgiwrap.conf
            - ./www:/var/www

The dafault.conf of nginx:

server {
    listen 80;
    server_name _;
    root /var/www;
    index index.html index.htm;

    location / {
        try_files $uri $uri/ =404;
    }

    include fcgiwrap.conf;
}

and fcgiwrap.conf:

location /cgi-bin/ {
  gzip off;
  root  /var/www;
  fastcgi_pass  unix:/run/fcgiwrap.socket;
  include /etc/nginx/fastcgi_params;
  fastcgi_param SCRIPT_FILENAME  /var/www$fastcgi_script_name;
}

in /var/www/cgi-bin/ I have test.py:

#!/usr/bin/python3
print("Test")

When I now go to http://localhost/cgi-bin/test.py I get:

[error] 31#31: *1 connect() to unix:/run/fcgiwrap.socket failed (111: Connection refused) while connecting to upstream, client: 172.18.0.1, server: _, request: "GET /cgi-bin/test.py HTTP/1.1", upstream: "fastcgi://unix:/run/fcgiwrap.socket:", host: "localhost"

What I want to accomplish, is basically to run a python on a host (local) from a website by pressing a button.
