auto disconnected after update to 1.7.22

[jptangchina]

I'm not sure if this is a bug. With server 1.7.22, and socket.io-client 2.5.0, the server auto disconnect with client because of ping timeout.(this works fine with server version 1.7.21)

Also this can be reproduce on your demo project:

BTW: It says that 1.7.22 supports for the v4 ping/pong mechanism, is that means I can use socket.io-client 4.x? I'v tried so but I got this error: It seems you are trying to reach a Socket.IO server in v2.x with a v3.x client, but they are not compatible (more information here: https://socket.io/docs/v3/migrating-from-2-x-to-3-0/)

I met the same problem.

That confused me as well, I also thought this library only supports socket.io v2. It seems like 1.7.22 broke the ping/pong support for 2.5.0 (socket.io-client) and that is causing the reconnect. With version 1.7.20 and 1.7.21 I get Unknown transport for request /socket.io/?EIO=3&transport=websocket on the server side.
The combination of 1.7.19 (netty-socketio) and 2.5.0 (socket.io-client) is working fine for me.

Does anyone know why they implemented v4 ping/pong support when it says in the readme that they support v2 clients?

Can you try version attached?

netty-socketio-1.7.23-SNAPSHOT.jar.zip

I just replaced jar to 1.7.23......A lot of netty's class are missing

[mrniko]

you need to copy netty libs from pom.xml since dep defined as a file.

[yujuncai]

eeeee.......I replaced jar to 1.7.23....auto disconnected never appeared again

[mrniko]

Fixed! Thanks for testing
