IOException when bedrock clients are kicked during login

[devdani1]

Describe the bug

Bedrock clients are encountering this error upon logging in

(java.io.IOException: An established connection was aborted by the software in your host machine)

This only occurs when they are banned and blocked by the bans plugin; they can log in normally if unbanned.

The weird part is that it only occurs if I log in while the server is still pinging (I still get the disconnect message in both proxy and geyser console).

If I log in after it pinged, I dont receive this error and see the intended message.

To Reproduce

1. Fresh install Velocity proxy and Geyser Standalone.
2. Add Litebans plugin and ban your account
3. Try to login with bedrock client while the server is still pinging

Expected behaviour

Show the disconnect reason that is being logged in proxy in the disconnect game screen.

Seems similar to #5291 - and as mentioned there, please provide a way to reproduce this without paid plugins

You don't need any plugins to reproduce this issue.
Simply create a new Proxy and a Geyser Standalone instance, then point the proxy to a server that is not online, to trigger a “server not found” error.

Try to join while the Bedrock client is still pinging.

Instead of "server not found" error you receive an IOException, but the proxy shows you were kicked for "server not found".

When servers are hosted remotely, the problem is worse because Bedrock clients take longer to ping, so players never see the real error message.

Able to reproduce with these steps. Thanks for providing them!
