nginx + gunicorn: deploy more than one Flask application

I already asked this in the Arch Linux boards but didn't get no answer. So I am trying my luck over here:

I am trying to set up nginx + gunicorn on my Arch Linux server to run multiple Flask apps. However I am seemingly failing in configuring nginx the right way to do so. When I just got one Flask app up and running everything seems to work fine. I included the /etc/nginx/sites-available and /etc/nginx/sites-enabled in my /etc/nginx/nginx.conf. I created a file "flask_settings" inside /etc/nginx/sites/available and linked it to /etc/nginx/sites-enabled. The file looks like this:

server {
    location /{
            proxy_pass http://127.0.0.1:8000;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;

}


}

I have a folder containing my Flask app (sample App, hellp.py) which i run with gunicorn in a virtual environment. I just run it using

gunicorn hello:app

If i visit my servers IP I can access the file and the different routes. Now I tried to set up another app creating another file in /etc/nginx/sites-enabled called flask2. It looks like this:

server {
    location /hello {
            proxy_pass http://127.0.0.1:8001;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;

}


}

I then try to run the app inside its very own virtual environment with

   gunicorn --bind 127.0.0.1:8001 hello:app

When I restart nginx afterwards, I am still able to access the first app and all of its routes, but if I try to access the other one by entering my servers IP + the router (after the "/"), nginx always tells me, that the sites cannot be found. Am I missing anything here? Any help is highly appreciated. Thanks in advance!
