I uninstalled the existing 1.0.15 version and installed the 2.0.0 ALPHA-14 version. Since I turned on the server, I keep getting the above error.

I just put Skungee into the Bungee server plugins folder and each server's plugins folder. Is my installation method wrong? Or is it Skungee's problem?

I'm also getting this error on Bungee's console.

Skungee 2.0.0 ALPHA-14
BungeeCord-Bootstrap:1.16-R0.5-SNAPSHOT
Paper 1.16.4 b416

The packet was incorrectly sent or was not a Skungee packet.

Make sure the versions are the same on the Spigot and Proxy side. Skungee 2.0.0 does not work with series 1.X

Needs debug log, enable debug and reproduce the error.
