TRY TO PLAY THE GAME VIA MOBILE INTERNET

If you have the choice, switching your ISP might also be effective. If not, try connecting to the game servers using mobile internet. After entering the game successfully, you can reconnect to your Ethernet or Wi-Fi and everything should work.

The issue can occur for a number of different reasons for various users, hence there is no one specific cause that can be identified. Changing the server region could resolve the issue if you are using a VPN and are experiencing it. The game server may flag and cause the issue if several players are accessing the game from a single server. The problem should not appear if you choose a server that is less likely to be utilised by other players.

CREATE A NEW STEAM ACCOUNT OR USE OTHER STEAM ACCOUNT

You should be able to play the game whether you use your existing other Steam account or create a new one. We tested this repair ourselves, and so far it has worked.

It appears that you are unable to use any VPN; nevertheless, several customers have claimed that ProtonVPN or ExpressVPN enabled them to get around the problem and download the game. You don’t have to worry about spending money because both of these VPNs offer a free subscription. I advise you to test them both since one is effective for a user while the other is not.
