Hi, I'm running a dedicated server at home. It's connected through a vpn to a vps so my friends can join. It works well, I'm running Homestead modpack. I pregenerated chunks using chunky (i know is not recommended but didn't think of installing DH until later).
Yesterday I installed DH on both, server and my client. Tested it, and everything was working (I'm connected to the server on my local network, not through the vps)
I told my friend to install dh and when he joins, "server doesnt support DH" shows up for him. Apart from that, since DH is installed I can't see his Skin, he can see mine.
Edit: Skin fixed, as expected, nothing to do with DH. Still no support from his end. I've connected through the vps, and for me it works. I checked, he is using the correct version of DH (2.4.5-b, same as me and the server).
