So we are having an issue within our Network. When using a 1.9.4 client players cannot connect to the Lobby, so we have to use the Fallback server instead. Along with HexagonMC Bungee we have ProtocolSupport and ViaVersion installed in the Lobby and Fallback server. Same setup, but I don't get why 1.9.4 clients can connect to the Fallback, but not the Lobby. Here is our plugin list for the Lobby and Fallback servers: Lobby: Spoiler: View Image Fallback: Spoiler: View Image Along with this we have a file in the root directory of our Lobby server named ProtocolSupport-errlog, but the file is empty. Apparently there is an issue, but we don't know exactly what it is. Any help would be greatly appreciated.
