Today, I just have noticed that there are a lot of people have been facing the Error Occurred (102) issue while linking device in Clash of Clans.
What is Error Occurred (102)?
This problem only shows up when you use the Link a Device option in game.
The linking system in game is based on the payment requirements of Google Play and App Store of your country. It means If there is a problem while connecting to the internet to load those payment requirements, your linking progress will be stopped.
How to fix the 102 issue while linking device?
It is very simple, just follow all these steps:
Create a Internet Hotspot on the original device (the device that you are playing Clash of Clans on).
On your new device, connect to that Hotspot and use it as the internet connection.
The 102 Issue has been solved!
This method works fine with me. If you have any problems or still can’t fix it, please do a comment then I will try to help you!
