Check Your Internet Connection

Poor and unstable internet connection may cause various technical issues especially when you are playing an online game.
If there is no issue with the Gigantic server status, it must be your internet connection that causing the issue.
In that case, you can check your internet connection by performing a speed test using internet speed testers.
After testing if you find any issue, you can fix it by rebooting your WIFI router.
If rebooting the router does not help you fix the internet connection problem, you should contact your ISP and ask for help.
Run the Game As An Administrator
An authentication error will appear when the game or any software does not have the required permissions to use the system resources.
