[Tutorial] How to use Hamachi

[Pandaman]

Hi everyone,i've read this tutorial and have opened port,setting up the hamachi and things,me and my friend,we can see each other in the lobby,but there is 1 problem,whenever i am the quest's host we can play normally but we always encounter a "broke up from group" if my friend is the one who host the quest (our latency between each other is very small and we have tried the 25% trick),i would be very grateful if someone can fix this,again thanks for the tutorial !
