In order to fix the issue, go to Start, type Windows Firewall and open the utility. Click Allow a program through Windows Firewall and check the box next to the Garena application. If you can't see the software in the Allowed Programs and Features window, use the Allow another program button to navigate to the Garena installation folder. Select its executable file and click Add. Also, make sure that your antivirus doesn't block the connection. If the problem is not solved, turn off your modem/router, wait 10 seconds and turn it back on. After that, go to Windows Firewall, press Advanced Settings and select Inbound Rules. Click New Rule from the right side, check the Port box, click Next, select All local ports and then Next again. Check the "Allow the connection" box, press Next twice and follow the instructions. As a final solution, uninstall your current version of the software and install Garena+.
