gunicorn setup for django channels - django

Question

My django app works fine on local machine as well as on Heroku, however I'm having troubles to deploy it do Digital Ocean Ubuntu 16.04 droplet. Followed this tutorial, app has started but websockets didn't work.
By running in terminal virtual environment: daphne -b 0.0.0.0 -p 8000 slist.asgi:channel_layer
and in second terminal window:
./manage.py runworker
The app works but only on port 8000. I can't access it on mydomain.com but only on mydomain.com:8000.
When I close terminal windows the site cannot be accessed.
What and how needs to be set for the site to run without my terminal windows and without the ':8000'?
My gunicorn.service file:
[Unit]
Description=gunicorn daemon
After=network.target
[Service]
User=kuba1
Group=www-data
WorkingDirectory=/home/kuba1/slistproject
ExecStart=/home/kuba1/slistproject/slistvenv/bin/gunicorn --workers 3 --bind unix:/home/kuba1/slistproject/slistvenv/src/slist.sock slist.wsgi:application
[Install]
WantedBy=multi-user.target
my Nginx settings:
server {
listen 80;
server_name server_name fortests.ovh;
client_max_body_size 20M;
location /static/ {
root /home/kuba1/slistproject/slistvenv/src;
}
location / {
proxy_pass http://unix:/home/kuba1/slistproject/slistvenv/src/slist.sock;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;
}
}

Answer 1

You have to proxy_pass the domain to that port 8000:
location / {
proxy_pass_header Server;
proxy_set_header X-Forwarded-Proto https;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_connect_timeout 10;
proxy_read_timeout 10;
proxy_pass http://localhost:8001/;
}

Answer 2

It should be:
proxy_set_header Connection "Upgrade";
Working config for me:
upstream websocket {
server unix:/path/to/daphne.sock fail_timeout=20;
}
location /url/socket/ {
try_files $uri #proxy_to_channel_app;
}
location #proxy_to_channel_app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
# enable this if and only if you use HTTPS
proxy_set_header X-Forwarded-Proto https;
proxy_set_header Host $http_host;
# web socket setup
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'Upgrade';
# we don't want nginx trying to do something clever with
# redirects, we set the Host: header above already.
proxy_redirect off;
proxy_pass http://websocket;
}
Daphne command:
daphne -u run/daphne.sock project.asgi:channel_layer
