Problem when creating sandbox account

[khang_nguyen_23]

Hello, I used to be able to create a sandbox account pretty easily using this link.

https://developer.cybersource.com/hello-world/sandbox.html

But now, every time I wanted to create an account all I get was this.

Registration Failed. Please try again.
