Failed connect to server

Tips to try :
1. If is using WiFi - then connect to router using a LAN cable ( local latency induced by WiFi transmission can result in d/c )
2. Close any other programs running ( as nvidia experience, overwolf, other game boosters ..etc )
3. Check if game is added to antivirus and firewall exceptions ( * in the past avast and avira was keep blocking the game once start to block and the only solution was to temporary unninstall those antiviruses )
4. Reset TCP/IP and flush DNS ( in case other programs set a custom DNS on windows settings it may trigger the error ) : https://forum.z8games.com/discussion/319365/failed-to-connect-to-server
( open command prompt as administrator )
5. Still not fixed send a support ticket as described on last point on the forum link above.
