Unexpected packet received during server login process!

[DJDanTheMan]

Hi,
I'm using Waterfall version git:Waterfall-Bootstrap:1.16-R0.5-SNAPSHOT:c031df1:395. However, when I try to login to one particular server which is my skyblock server I get this error on the proxy.
[18:32:20] [Netty Worker IO Thread #2/INFO]: [_DJDan] <-> ServerConnector [skyblock] has connected
[18:32:20] [Netty Worker IO Thread #2/ERROR]: [_DJDan <-> ServerConnector [skyblock] - encountered exception: net.md_5.bungee.util.QuietException: Unexpected packet received during server login process!

Is it possible to fix this? I can't seem to replicate it on my own private server so I don't know how I can resolve this issue.
