This solved my lag issue!!!
So like so many of you I've had the rubber band problem, things not loading. I can move in the world and see other players do things, npc's and mobs not loading in till after 1-5 mins.
Tried several vpn's and pingzipper, and it didn't work.
Turns out it was as simple as opening the right ports.
For those of you who knows what to do..
(Edit: Opening port 443 can be unsecure, so I closed that one again and it's still working for me).
Start port: 443
End port: 443
--------------
Start port: 54992
End port: 55551
And for you who doesn't, just follow the steps in the link bellow.
