Hi,

Hi,

Your meter is returning GloConfirmedServiceError. Because I don't know the authentication and block cipher keys I can't tell the reason why it fails.

We'll add better support for GloConfirmedServiceError so it's decrypted. What programming language you are using?

BR,

Hi Mikko,

Hi Mikko,

I am using c# programming language.

Also, You can use key "0123456798ABCDEF" to verify fail reason.
