I added a few addons when I was playing, but I added them before, and I can play normally. But this time I went in and said "Can't connect to the world. Please check your Internet and try again." I tried many methods, such as re-entering, shutting down and restarting, but they all didn't work. And only that archive is like this, other archives can play normally. I am not going into other people's world, but playing solo! This archive is really important to me! !
