So for the past few weeks ever since the nether update in minecraft, my friends have not been able to join my world but I have been able to join theirs with no problem. I have uninstalled and reinstalled minecraft, done a hard reset and a reset console but keep data, made sure my NAT type is open and that all my ports are open and working properly and still nothing. What am I supposed to do or is this issue going on for other players? It's really frustrating because me and my friends just want to get back to working on our stuff in our creative world.
