My Environment

Proxy Version: Velocity 3.3.0-390
Server Version: 1.20.4+Fabric-0.14.25 with latest Via* plugins
Server Mods: CrossStitch 0.16 + FabricProxy-Lite 0.27
Client Version: Vanilla 1.16.5 and Vanilla 1.18.2 Tested

Description

Hi, Velocity Team!
I got this error when using low version clients (I've tested 1.16.5 and 1.18.2) to connect to a 1.20 server, is there any idea on this:

[01:28:39 ERROR]: [connected player] XXX (/XXX.XXX.XXX.XXX: XXXXX): unable to connect to server XXX

We do not support protocol hacks, and this is generally not the place for support (the forums/discord are a better place for that)

Sorry but what do you mean by "do not support protocol hacks"? Does that mean Via* is not supported here? I was thinking whether this is related to #1251.

correct, we do not support Via, nor can we generally provide advice around such generic issues on the issue tracker

Okay, seems duplicated with ViaBackwards#642.
