i have been trying to join my friends world for the past week and it wont let me. it could because of the NAT thing based on what i saw on some post of other games. but i don’t know how to fix that and if it causes me needing to unplug or do anything physical or whatever with the internet box thing i cant. since my family would yell at me for a while about it. but other then that it wont let me join. i usually have good internet. well that is if not everyone in my family is on electronics or anything that might require really good internet. it did let me join them for like a month or two but after that it kinds stopped and cant join. anyone know about this or at least can help?
