disable all antivirus software, firewall software, windows defender, smartscreen, other defend services your PC, check a corrcting settings internet in your router and windows (dns services).

If the problem persists, please contact your Internet service provider regarding the unavailability of the server named alex789.at.ua

Also, you can try running DayZ Fixer in the game folder and click "Fix problem connections", but this may not help with solving the problem.

download these files and unpack them into the game
