    So I'm trying to make a modded server for me and my friend to play on, i download all the mods on the aternos server and on the client but It wont let me join and instead gives me an error "Connection Closed - Mismatched Mod Channel List" and on the server list there's a red X saying "Incompatible FML Modded Server", all the mods on the server and client match and are the same versions. Same forge version too.
