So I had no clue what topic to put this under because its not really modding with forge but modding forge itself. So I have terrain generation mods that are only server side and Bungeecord that has Geyser packet translator so people on bedrock edition can play as well, but when a bedrock player connects it gets a unknown packet error. I tested the proxy on a Spigot server verifying it was forge. With no mods installed I still get the error. I got a wireshark log of it all and I found the packet where it aborts the connection due to the invalid packet but I have no clue how to stop it. When I still had the mods installed I disabled the forge handshake protocol but it did not fix the issue. If you know what part of forge is doing this or a way to fix it all together that would be awesome. I know modifying forge can end really baddy (definitely the handshake protocol) but I think that is my only fix here. Im open to any suggestions tho. I have run out of ideas to fix it so any help would be nice. Also it seems the packet id causing the connection error is 0xFE but im not sure cause the client also sends back a packet with that ID. I have a whole bunch of info collected so if you need any more information on the issue, I willing to give it, just not the ips on the wireshark log.
