Closing KiwiIRC in browser does not disconnect it from IRC server

[landergate]

Using web-client, hosted by KiwiIRC, i see that it's closing connection from IRC server correctly when user closing tab or window.

When using self-hosted KiwiIRC, I'm experiencing this:

1. User closing KiwiIRC window
2. User still being online on IRC server
3. User being kicked from server after timeout [Ping timeout: 186 seconds].

Server: UnrealIRCd

1. What version of kiwiirc are you using? (check package.json)
2. Is this happening for all users or just yourself?
3. Are you using any reverse proxies?
4. Are you using SSL to connect to your kiwi server?

Is this happening for all users or just yourself?

For all users using our hosted KiwiIRC

Are you using any reverse proxies?

Yes! Nginx config looks like this:

server {
    server_name irc.ourdomain.net;

    listen     443 ssl;

    ..................

    location / {
            proxy_set_header X-Real-IP  $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $host;

            proxy_pass http://10.0.2.4:7778;
            proxy_redirect default;

            # Websocket support (from version 1.4)
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
    }
}

Probably it must be the issue? We used practices from here: https://kiwiirc.com/docs/installing/proxies

Are you using SSL to connect to your kiwi server?

No (kiwi and irc server are near to each other)

[landergate]

Tried some experiments with

keepalive_timeout 3s;
send_timeout 3s;
client_header_timeout 3s;
client_body_timeout 3s;

proxy_read_timeout 5s;
proxy_send_timeout 5s;
proxy_connect_timeout 5s;

but user keep disconnecting only since 40-60 sec after closing browser tab.

A few people have reported that enabling SSL on your web server (nginx) solves this kind of issue. This seems to increase stability as some firewalls/proxies actually drop some of the websocket frames.

@prawnsalad Thanks for reply! Well, we have SSL-only already. =]

kiwiirc.com being served with another frontend software, not nginx?

I'll just continue my experiments to find a solution.
