If you are having trouble connecting to any game under Game321 there could be a few things that could cause this. To troubleshoot follow the below steps:
1) Check your Internet Connection. If it isn't working neither will the game!
2) Make sure the Game is online. Sometimes we need to bring the server down to make maintenance. Announcements about these downtimes can be found on the window that appears on the game official website or the forum announcement.
3) Make sure that your anti-virus/internet security programs are not blocking Game321. If they are add Game321 to the allowed list or lower the access settings.
4) If none of these steps work, contact online staff on the right sidebar of the Support page. Click the "Chat Now" tab and online staff will follow up to troubleshoot the issue further.
