Description

I am using two servers connected by proxy (lightfall). However, when moving from server A to server B, the connection is disconnected with the error (images). Strangely, few users were able to move (the majority of them were disconnected). I don't know how to fix it. Sincerely, ask for your help. Arclight version : horn/1.0.5 Minecraft 1.19.2 Forge 43.3.8 lightfall version : 1.20-3 lightfall client version : 1.1.0
