Multiplayer problem

Hello, I live in France and my brother live in Timor leste (he have a bad internet connection)

we have tried to create a servor /world in multiplayer following instructions on internet, but we can't connect to the each other's worlds, once we try to connect to a world/servor there is the following error message that I can't connect to it and same for my brother.

we are friends in the game and see that we are connected, but we can't meet in official servers too or play together.

i bought the game to play with him, thank you for helping us.

have a great day
