I wanted to set up a Debian 10 Minecraft server in version 1.8.8 (Spigot / Bukkit) and I get strange error messages when I log in:

[11:45:08 WARN]: An exceptionCaught () event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.

This error message keeps coming back infinitely until you stop the server. In Minecraft the error message comes up:

Internal Exception: java.io.IOException: An existing connection was closed by the remote host

I look forward to an answer.

The server is down
