Ejabberd: Websocket + NGINX Proxy

[CreativeWolf]

What version of ejabberd are you using?

Ejabberd 18.06

What operating system (version) are you using?

Ubuntu 16.04

How did you install ejabberd (source, package, distribution)?

Source

What did not work as expected? Are there error messages in the log?

When ejabberd is accessed through websocket directly ws://chat.test:5280/ws (Using Stropje.js) I'm able to connect to the server

However, if I use http://chat.test/ws I'm getting 400 Bad Request

Here's my NGINX config - Where chat.test is a virtual host

location /ws {
    proxy_pass http://127.0.0.1:5280/ws;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

Appreciate any pointers please.

Thanks

Seeing the same with Conversejs, works with the included http_fileserver though.

Update:

1. Changed the nginx config by adding the line proxy_http_version 1.1;

location /ws {
    proxy_pass http://127.0.0.1:5280/ws;
    proxy_http_version 1.1;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

1. When connected to the through websocket directly ws://chat.test:5280/ws using Strophe - This is what I see in the log file

I see the request coming in as a GET request

However while using nginx proxy http://chat.test/ws

2018-12-24 01:11:05.622 [debug] <0.16554.0>@ejabberd_http:init:147 S: [{[<<"ws">>],ejabberd_http_ws},{[<<"bosh">>],mod_bosh},{[<<"api">>],mod_http_api},{[<<"admin">>],ejabberd_web_admin},{[<<"http-bind">>],mod_bosh}]

2018-12-24 01:11:05.623 [debug] <0.16554.0>@ejabberd_http:process:392 [<<"ws">>] matches [<<"ws">>]

I see the request coming in as a POST request

What could be causing this?

Appreciate any pointers please.

Hello,

I am guessing that this will be fixed if you use ws://chat.test/ws url (strophe will use bosh protocol for http:// urls, and thats not compatible with websocket connection).

Thanks @prefiks

Adding this line to establish the connection indeed solved the issue!

Chat.connection = new Strophe.Connection("ws://chat.test/ws/");

Thank you!
