Disconnection messages are not displayed correctly

[OtakuSweett]

Describe the bug

Description:

When a player is kicked or banned on a server using GeyserMC, Velocity, and specific plugins like LiteBans and DeluxeMotd, the expected kick/ban message is not displayed. Instead, the player encounters an "Internal Exception: java.nio.channelsClosedChannelException" error. This issue is specifically tied to certain actions (kicks, server maintenance) and does not occur with all types of messages, such as whitelist, anti-bot, VPN messages, etc.

Actual Behavior:

Instead of the expected message, the player receives the "Internal Exception: java.nio.channelsClosedChannelException" error. However, the correct kick message is logged in the server console.

To Reproduce

Installation: Install GeyserMC, configure proxy protocol and proxy mode.
Configuration: Configure remote and local connections in GeyserMC.
Plugins: Install and configure the mentioned plugins, especially LiteBans and DeluxeMotd.
Action: Kick a player or put the server into maintenance mode.
Result: The player receives the mentioned error, but the correct kick message is shown in the console.

Expected behaviour

Upon kicking or banning a player, the server should display the configured kick/ban message from plugins like LiteBans or DeluxeMotd to the player.

are disconnection messages only not shown when using proxy protocol? or does it also occur without it?

[OtakuSweett]

only with proxy mode enabled is that messages are not displayed
