So, I'm trying to make a hub and people can choose between 2 servers. I'm using bungee hub, for my hub. I tried other Hub Plugins, but their all buggy. I don't know if it's my configuration's fault, or BungeeHub's fault.Maybe can you advice me some good hub plugins? Please mind the SOCKET because i didnt find any socketexpection at google. Well that's it. Hope you can help me out, I will really appreciate that So, here are my configuration files.
