hello i just tried to use mudfish for korea league of legends but it doesnt allow me to login and i checked its vpn problem, but when i tried to use my own WIFI it works, i think its mudfish problem, any solution? thanks
Did you try to change a mudfish node based on FAQ - Nodes section for your game item? I think most of mudfish korea nodes could be blocked by the game publisher so I guess few of them are allowed to be accessed. 
Sorry for this inconvenience.
