checking versions means you are ip restricted because you have made too many games, joined too fast. now there is a similar error where if you load d2 and it just says unable to connect this is from using a vpn.
so mark when checking version happened then if this happens for more then 20 minutes you are going to be restricted for up to 2+ weeks up to 20 ish days.
changing the cdkey wont help, uninstall wont help you just need to wait it out.
when making a game make sure and wait 1 minute, dont be in game for less then 1 minute i try to be doing stuff for about 6-9 minutes per game. if you leave early make sure and add what ever early time you are out of game into your next game delay timer.
Ty, but this time I didn't change games fast, I was ingame, disconnected, reconnected, kicked again and reconnected again, then i left the game for the night.
I just changed IP for mobile hotspot, it doesn't helped at all
