Error after trying to test a pay suscription "Error registrando la llave pública: $$$, o validando el token de autenticación".

Hi,

I was testing your plugin and apparently fits very well to my needs in a store that I'm developing. However, there is a issue when I try to test a payment. The error exactly that is showing is "Error registrando la llave pública: $$$, o validando el token de autenticación". I review a couple times my keys and is setting properly.

I was looking your readme and in the steps mention something about payU which let me a bit confused 'cause I understand that these platforms are different. Am I right?

Let me know if you need more info about it

Thanks in advance.
