My boyfriend and me cant play at the same time on different pc and different accounts

Hello,

my boyfriend and i have both our own accounts and bought poe2 on them.

He is playing on his Account at his pc.
I am playing at my account at my pc.

If (for example) i am already playing for an hour and my boyfriend joins later in the game at his pc.. i have so many laggs… spike… glitching around the map etc.

Same if he is playing for some time and i am joining later.

Our internet connection is way more than stable. Our hardware is up to date.


Does poe 2 not allow 2 people from the same house/router ?
Are there problems because we play from the same ip or something?
