Решил проблему, надуюсь кому то еще пригодится.
Мой конфигурационный файл для сайта:

upstream web-portal {
    server 127.0.0.1:5050;
    keepalive 15;
}

server {
    listen 80;
    server_name demo.portal.ru;
    root /var/projects/web.portal/current/public;
    access_log /var/log/nginx/web-portal.log;
    error_log /var/log/nginx/web-portal.error.log;

    location / {
        proxy_pass http://web-portal;

        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    location ^~ /socket {
           rewrite  ^/socket/(.*)  /$1 break; #used to send request to base url
           proxy_pass http://web-portal;
           proxy_redirect off;
           proxy_pass_request_headers on;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header Host $http_host;
           proxy_set_header X-NginX-Proxy true;
           proxy_set_header X-Forwarded-Host $host;
           proxy_set_header X-Forwarded-Server $host;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_http_version 1.1;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection "upgrade";
           proxy_set_header Host $host;

    }

    location ~* \.(?:jpg|jpeg|gif|png|css|js)$ {
        expires 30d;
    }
}
