Very weird problem

I am having a <very> strange sudden problem with my server. Nobody can connect as it says "Could not connect to the login servers, are they down?" Even though they are 100% online.

This is my bungee console: http://hastebin.com/ukowahugop.avrasm

This is the startup of my Hub: http://hastebin.com/awirozipeb.avrasm

Help is <greatly> appreciated

EDIT: I restarted all the servers multiple times, and it is now back online, although If anyone knows what the issue is here,...
