Error during WebSocket handshake, I use nginx

lqzerogg

well, though nodebb websocket cannot be connected, a simple websocket server I wrote can be connected. I use the same config :

  upstream acp_io_nodes { 
    #ip_hash; 
    server localhost:3434;   
  } 
 server { 
    listen       80; 
    server_name  test1-forum-acp.ezsport.cc; 
    location / { 
      proxy_pass http://acp_io_nodes; 
      proxy_read_timeout 300s; 
      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_http_version 1.1; 
      proxy_set_header Upgrade $http_upgrade; 
      proxy_set_header Connection $connection_upgrade; 
               } 
       }

here is my server's code:

console.log("Server started"); 
var Msg = ''; 
var WebSocketServer = require('ws').Server 
    , wss = new WebSocketServer({port: 3434}); 
    wss.on('connection', function(ws) { 
        ws.on('message', function(message) { 
        console.log('Received from client: %s', message); 
        ws.send('Server received from client: ' + message); 
    }); 
 });

Hope someone will rescue me soon.

Strange, i responded to the "try to reply" message but its gone now. Nevermind!

@jenkler well, that's because I edit it.

The normal way to configure nginx is to create an nginx config file in /path/to/nginx/sites-available/. You can copy one of the templates from docs.nodebb.org.

You then need to create a symlink from the file (I'll call it forum.example.com) in sites-available to sites-enabled

ln -s /path/to/nginx/sites-available/forum.example.com /path/to/nginx/sites-enabled/forum.example.com

You don't seem to be using our nginx templates at all. Any reason why?

lqzerogg

@pitaj because my nginx has other services. I have to follow previous configs. Anyway, I'll try what you said.

lqzerogg

@pitaj
My nginx dir only has these dirs:

@pitaj My nginx directory only has these sub dirs:

 client_body_temp  conf  fastcgi_temp  html  logs  proxy_temp  sbin  scgi_temp  uwsgi_temp

And even I do what you said, nginx still not working. I seems that my nginx can only set config by conf/nginx.conf file. sites-available/ and sites-enabled/ seems useless to me.

@pitaj Depending on the OS nginx is set up differently, you can't push sites_enabled/ and sites_available/ on people. It's mostly a Debian/Ubuntu thing

@lqzerogg Can you show us your config.json?

@julian thx, I've solved this problem. But I can't post my solution because the stupid robot marked my post as spam.

After a hard time debugging, I found out that it's not because of nginx setting. It is because I set a "cookieDomain" config. After I remove this one, it works properly. I modify source code and fix this problem. Maybe it's not a good solution, but it works for me.

file: src/socket.io/index, line:45

// other code
// added code, force to resign variable
		domain = parsedUrl.hostname;
// comment these codes
//		if (!domain) {
//			domain = parsedUrl.hostname;	// cookies don't provide isolation by port: http://stackoverflow.com/a/16328399/122353
//		}
// other code

julian

... do you need to set cookieDomain? You're probably better off unsetting that config instead of commenting out code.
