Socket.io 和 NGINX。无法为 sockets 工作进行配置

Question

I have my backend with socket.io and i want to configure socket.io with nginx. After nginx following configurations, I am able to make my routes other than sockets to work but my sockets are not working.

server_name yourdomain.com www.yourdomain.com;

location / {
    proxy_pass http://localhost:5000; #whatever port your app runs on
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
}

What are configuration that I need to do in (sudo nano /etc/nginx/sites-available/default) file to make sockets work.

Did you try adding

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

to your location config?
