Socket io issue?

Normando

Hello.

I have runing 0.5.5 nodebb forum. Sometimes The right sidebar plugin (Recent posts) can't fill nor load notifications, as you can see in the image. When I hit CTRL + F5 on Chrome 5 times, all the site runs ok, but most of the time not. Can I do something to fis this issue?

I am using MongoDB as backend, Node 0.10.33 on a Centos 6 64bits server.

Thanks for the help.

I have some issues too.. if its open for too much time.. i got lots of socket io errors on the console.. and the browser gets heavy..

julian

Hm, interesting. @Normando can you confirm @Leonardo-Galani's claim that this happens only when the browser session is open too long?

@baris is looking to upgrade NodeBB to socket.io 1.0, which may address this.

baris

Are you guys using clustering and did you setup redis? Is the browser doing xhr polling?

Normando

hmmm... not for me, the browser run smothly. At least as I can see.

@julian I am not using clustering, so I not set the "cluster" key in config.json, nor setup redis. Thanks

EDIT: Also this happens when I writing a post and the right side to preview does not fill with the parsed content I writing

Sorry my bad english

How do you start nodebb? Are you using nginx to proxy requests? What is the version of nginx?

Normando

Yes, I am using nginx:

rpm -q nginx
nginx-1.6.2-1.el6.ngx.x86_64

Starting with ./nodebb start

This is my config.json file:

cat config.json
{
    "base_url": "xxxxxxxxxxxxx",
    "port": "10000",
    "secret": "xxxxxxxxxxxxxx",
    "bind_address": "127.0.0.1",
    "database": "mongo",
    "mongo": {
        "host": "127.0.0.1",
        "port": "27017",
        "username": "xxxxxxx",
        "password": "xxxxxxx",
        "database": "nodebb"
    },
    "bcrypt_rounds": 12,
    "upload_path": "/public/uploads",
    "use_port": false,
    "relative_path": ""
}

Did you setup nginx to proxy websockets check out this guide https://docs.nodebb.org/en/latest/configuring/proxies/nginx.html

Normando

@baris yes.

server {
  listen       80;
  server_name *.xxxxxxxxxx.com.ar;
  return 301 $scheme://xxxxxxxxxx.com.ar$request_uri;
}


server {
    listen 80;

    server_name xxxxxxxxxx.com.ar;

    access_log  /var/log/nginx/vapor-access.log;
    error_log   /var/log/nginx/vapor-error.log;

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-NginX-Proxy true;
    proxy_redirect off;

    # Socket.io Support
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";

    gzip_types      text/plain application/xml application/x-javascript text/css application/json;

    location @nodebb {
        proxy_pass http://127.0.0.1:10000;
    }

    location ~ ^/(images|language|sounds|templates|uploads|vendor|src\/modules|nodebb\.min\.js(\.map)?|stylesheet\.css|admin\.css) {
        root /opt/vapor/nodebb/public;
        try_files $uri $uri/ @nodebb;
    }

    location / {
        proxy_pass http://127.0.0.1:10000/;
    }
#    error_page 405 = $uri;
}

If nodebb is running smoothly for awhile and later decides to stop working then there may be an issue with socket.io connections expiring or timing out...

Normando

I can confirm that there is no nginx issues, because I was switched proxy off and use port and I get the same issue.

Also I was disabled all plugins and the issue continues. So, I am thinking about the Lavender template. Tell me if I am wrong.

This issue with socket.io is very very irritating because 50% of forum features not working.

Thanks guys for the help.

Normando

Why not happens this issue here and is present in my forum? Can you test it?

This is the nginx timeout error, because socket.io

2014/12/01 02:09:12 [error] 29961#0: *166 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 201.235.8.88, server: vapeandoargentina.com.ar, request: "GET /socket.io/1/xhr-polling/r3XfrKkqSy2ywgDXKA6S?t=1417410491280 HTTP/1.1", upstream: "http://127.0.0.1:20000/socket.io/1/xhr-polling/r3XfrKkqSy2ywgDXKA6S?t=1417410491280", host: "vapeandoargentina.com.ar", referrer: "http://vapeandoargentina.com.ar/"

Are you using cloudflare? They don't have websocket support on the lower plans.

Normando

@baris said:

I can't understand your question. We are not using cloudflare. We have only activated "Spam Be Gone" plugin and only use reCaptcha.

You mean this?

I don´t know where come this. I suspect from lavender template?

baris

Those should be fine we have them on this site as well and sockets work. I meant https://www.cloudflare.com/ but apparently you don't use them so I am not sure what the problem is.

Sounds like proxying is not configured properly.

@Normando Give the latest commits a go Socket.IO 1.0 is merged in, undergoing testing at the moment.

a_5mith

@Julian, aand the smilies are broken again. You'll probably have this in your console:

1/12 13:57 [20209] - warn: Route requested but not found: /topic/1127/undefined/plugins/nodebb-plugin-emoji-extended/images/thumbsup.png
1/12 13:57 [20209] - warn: Route requested but not found: /topic/1127/undefined/plugins/nodebb-plugin-emoji- extended/images/thumbsup.png

But many times.

Normando

@baris No, proxy is ok. This happens without the proxy. I posted the nginx error onlyfor reference.

About cloudflare I was removed from header.tpl and relodad nodebb, but the issue still there.

I will test the new merged with Socket.Io 1.0.

Thanks!

a_5mith

@Normando I suspect what you removed was the ie9 compatibility.

Normando

@a_5mith yes. I now restore again.
