How to fix the issue: "Server error occurred" or "An error occurred" when you redeem Garena Shells in the game?

We recommend that you redeem your Garena code for Diamonds on the Singapore website here.

The reasons why this problem may occur are:

1. You entered the Garena card code incorrectly.

2. You entered the verification code at the bottom incorrectly too many times.

Simple Solution:
Just turn off your mobile phone, restart it, and then try accessing the website again.
