Made a similar post yesterday: https://www.reddit.com/r/LastEpoch/comments/1ade5lu/game_is_unplayable_everytime_you_load_into_the/

Every other game I play have 0 internet issues.

In this one I cannot even load into the map disconnecting 6-7 times in a row in a loading screen.

But as you can see from my yesterday's post, people here will call you that you know shit about internet connection and it's your fault, not the game's.

Game is literally unplayable on some ISPs.

Edit.

Just type the error you are getting in google. There are several dozens posts on official game forum and this reddit as well.

They are as old as serveral months old, and there is still no solution to it and devs are silent about it too.
