Xbox Coop (Xbox) connection Failed

I been trying to create a new farm (game) with some friends, but every time we got the same message "connection lost/ failed" I doesn't matter what we try (reset our modem, delete the game and download it again, check our NAT, build) , we can't play or create a new farm.
This is not new, this problem appears maybe 3-4 months ago

And by the way we try the code to join** but it doesn't appears
