I try to join a specific friend's server (Singleplayer map opened for LAN+Hamachi), Loading terrain...  then the game loads the skybox in then the game crashes with the message:

java.io.IOException: An existing connection was forcibly closed by the remote host

or I just get the Timed out message

I can look around ingame before it crashes, but there is only skybox, loads in the player list and their character icons, sometimes the animals too...

1.) This friend of mine lives very close to where I live, has same ISP, might be a problem?

2.) Tried reinstalling Minecraft and java, did not help

2.) Tried with wifi and cable internet connection, did not work with neither, other people can connect and play easily, my internet is quite fast too

I hope there is a solution, already tried some supposed solutions from other threads, if any further info is needed, I am happy to provide, thanks.
