Unable to implement websocket with Nginix and Daphne

Question

I am trying to setup websockets on my django application using Daphne and Ngnix. On my local setup everything works as expected but when I have uploaded to the server the websockets do not respond. This is Nginx.conf file:

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
        worker_connections 768;
        # multi_accept on;
}

http {

        ##
        # Basic Settings
        ##

        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;
        # server_tokens off;

        # server_names_hash_bucket_size 64;
        # server_name_in_redirect off;

        include /etc/nginx/mime.types;
        default_type application/octet-stream;

        ##
        # SSL Settings
        ##

        ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLE
        ssl_prefer_server_ciphers on;

        ##
        # Logging Settings
        ##
 access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        ##
        # Gzip Settings
        ##

        gzip on;

        # gzip_vary on;
        # gzip_proxied any;
        # gzip_comp_level 6;
        # gzip_buffers 16 8k;
        # gzip_http_version 1.1;
        # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

        ##
        # Virtual Host Configs
        ##

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;

        client_max_body_size 10M;
}

and this is my sites-available file which is accessed by Nginx:

server {
    server_name 139.59.9.118 newadmin.aysle.tech;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/django/AysleServer/src;
    }

     location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }

    location /wss/ {
        proxy_pass http://0.0.0.1:8001;
        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;
    }




    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/newadmin.aysle.tech/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/newadmin.aysle.tech/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
    if ($host = newadmin.aysle.tech) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    server_name 139.59.9.118 newadmin.aysle.tech;
    listen 80;
    return 404; # managed by Certbot


}

and this is my daphne.service file:

  GNU nano 4.8                                                                 daphne.service

[Install]
WantedBy=multi-user.target

I tried sending a websocket request like this:

ws://newadmin.aysle.tech/ws/test/
ws://newadmin.aysle.tech:8001/ws/test/

But I do not get any response back. I tried checking the log files for error but there is no error. My guess is Nginx is not forwarding the request to Daphne. Probably a configuration issue. But I do not know what to change. Please help me with this. Thanks for your time in advance. Please note that I am also using Gunicorn to handle the HTTP request and they work as expected.

Since you are using ssl in your nginx config, you also have to use wss instead of ws as the scheme.

Also your location is /wss/ so your uri should use this location too.

Try this for a request from the client:

wss://newadmin.aysle.tech/wss/test/

If this doesn't work, you could also check, if your host does even allow WebSockets, or if you have to activate it. For example, I used a Djangoeurope server and had to activate WebSockets for the uri.
