Clash of Clans keeps closing and disconnecting due to an unstable internet connection. Plus, your ISP or WiFi network admin may throttle CoC traffic. You need a VPN with fast and secure tunneling protocols to game comfortably without crashes or disconnects. Bear in mind the game may crash if you’re using a jailbroken iPhone or iPad. Additionally, Clash of Clans installation problems may be caused by geo-restrictions in certain countries, like Vietnam or Russia. Geoblocks may also prevent you from receiving a registration or password restoration verification code. Besides, the game may be absent from your local app store. However, a VPN with a global server network lets you download and play CoC from any location.
