Every time any player tries to get on my modded server they get disconnected instantly with the console log going as follows:

[14:13:42] [Server thread/INFO]: WhoCanPeliCan lost connection: TextComponent{text='Disconnected', siblings=[], style=Style{hasParent=false, color=null, bold=null, italic=null, underlined=null, obfuscated=null, clickEvent=null, hoverEvent=null}}
[14:13:42] [Server thread/INFO]: WhoCanPeliCan left the game

I do not know if this is due to my 1.7.10 modded server http://www.technicpack.net/modpack/shattered-glitchverse.878399 or due to some other reasons. Please help as this seems to be a possible common problem
