Bungeeguard not working

[PatrickMSM]

So when i try to connect through my proxy, it says: Unable to authenticate - no data was forwarded by the proxy.

This is the error i get on my origin server: [17:52:31] Denying connection from 127.0.0.1 - - reason: INVALID_HANDSHAKE

I am using spigot 1.16.5 (3053-Spigot-4225eac-69c8e78) for my origin server. I can't use paper because it patches dupes that i need on my smp.

I am using Flamecord for my proxy.

Plugins on the proxy: none except BungeeGuard. Plugins on the origin: AdvancedBan, EntityTrackerFixer, LoginPlus, FastAsyncWorldEdit (WorldEdit), ViewDistanceTweaks, AutoRestart, Essentials, SinglePlayerSleep, ABC, BungeeGuard, ProtocolLib, Orebfuscator
