MHFU cannot host a quest but can join them

[Jeremy MHFU]

So here is my situation I play on a android phone s5 connected to my home wifi and I successfully can play with others as long as I join there quest they set up. But if I set up a quest I will be broken away from the group? I believe the rest of the group members remain together but I am not sure. I believe I saw a post a while ago that said it had something to do with router firewall settings on your pc but as I am playing on my phone I do not know what I need to do. I would really like to fix this as I love this game and I am very happy to see people still playing it fairly regularly in the online gathering halls any help would be much appreciated.
