Hello,

I followed some guides i saw here in order to play online at mhfu with a friend. We both did all was told in these guides. But when i host and he tries to enter in the online hall his game freeze and he can't connect and it's the same for me when he the host.
We already tried with both amachi and tungle but no resuslts.
What should we do ?

Thanks.
