ok thx but do you still ned to do this for every back end server cus the proxy is on minhut ? Minehut External Servers Docs (notion.site)

thank you

I am attempting to set up a server on fabric 1.20.4 with both BetterEnd and BetterNether fabric mods. Currently I have added the bclib, betterend and betternether mods, all fabric versions 1.20.4 in the mods folder on minehut, and client side with the fabric api in my mods folder. When attempting to join the server I get Connection Lost, "Internal Exception: io.netty.handler.codec.EncoderException: java.io.IOException: Can't serialize unregistered packet" Does anyone know what I can do to fix this error code? or what it means?

Yes. This video should still be relevant:

yes but what setting would i have to change for it to work

My bad, sand duping cannot be enabled via the paper YML file. You would need a plugin to get it to be enabled. Here is a plugin you can use: https://dev.bukkit.org/projects/gravity-control
