Invalid regex in trigger-message will cause it to fail in a way hard to debug

[ghost]

An exception is thrown here, not printed, caught by me with java debugger

LimboReconnect/src/main/java/net/elytrium/limboreconnect/listener/ReconnectListener.java

Line 58 in 6615aa9

if (kickMessage.matches(CONFIG.triggerMessage)) {

This leads to ghost-like state, where player is not on backend and not in limbo, just waiting for time out.
Writing anything in chat in that state leads to issues like #21 #23.
I'm not an expert in Java, but I would suggest adding try-catch blocks there, kicking player on any errors.
Also, precompiling Pattern in advance while loading config can make this error more descriptive. Also javadoc says it can squish a bit of performance that way.

Also your maven repo is down for some reason, I can't PR a fix.

Oh, seriously... I never thought that issue was in regex.
