Django Daphne Websocket Access Denied

We need to establish a "Web socket connection" to our AWS servers using Django, Django channels, Redis, and Daphne Nginx Config. Currently local and on-premises config is configured properly and needs help in configuring the same communication with the staging server.

We tried adding the above config to our servers but got an error of access denied with response code 403 from the server for web socket request.

below is the Nginx config for staging

server {
    listen 80;
    server_name domain_name.com domain_name_2.com;
    root /var/www/services/project_name_frontend/;
    index index.html;

    location ~ ^/api/ {
        rewrite ^/api/(.*) /$1 break; 
        proxy_pass http://unix:/var/www/services/enerlly_backend/backend/backend.sock;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
        proxy_set_header Host $host; 
        proxy_read_timeout 30;
        proxy_connect_timeout 30;
        proxy_send_timeout 30;
        send_timeout 30;
        proxy_redirect ~^/(.*) $scheme://$host/api/$1; 
    }

    location /ws {
        try_files $uri @proxy_to_ws;
    }

    location @proxy_to_ws {
        proxy_pass  http://127.0.0.1:8001;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_redirect off;
    }

    location ~ ^/admin/ {
        proxy_pass http://unix:/var/www/services/project_name_backend/backend/backend.sock;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
        proxy_set_header Host $host;  
        proxy_read_timeout 30;
        proxy_connect_timeout 30;
        proxy_send_timeout 30;
        send_timeout 30;
        proxy_redirect off;
    }

    location /staticfiles/ {
        alias /var/www/services/project_name_backend/backend/staticfiles/;
    }

    location /mediafiles/ {
        alias /var/www/services/project_name_backend/backend/mediafiles/;
    }
    location / {
        try_files $uri /index.html;  
    }

}
