Before diving into the thick of the troubleshooting, it is important to understand that your Internet Service Provider
(ISP) and the way you share the connection speed
play a huge role in how you experience the game.
To try and improve your overall connection to the game and its features, please try the below steps in the order listed:
• Enable UPnP
Please contact your ISP for additional information and help with enabling this feature.
