Error while trying to connect on the server

[AnythingMayBe]

Hello,

The fork used can be found on the Karhu Anticheat Discord server (https://discord.gg/cMY4xKRrW4).
I'm using the latest version of BungeeGuard and ProtocolLib.

After logging in on the proxy, my lobby server gets this error :

[09:42:08 WARN]: [BungeeGuard] Denying connection from 127.0.0.1 - 881ab704-8266-391d-a1f5-51b3aadf3b03 @ MTI3LjAuMC4x - reason: NO_TOKEN
