Basic Example PaaS API Not Working

[FastSnail]

Hello,
I am trying to run the PaaS API. I am using the CnP Basic Example provided in the library, below. I have only changed orderMode from Test to Production. It always come back as "decline". It looks that I have everything I need in the SFDC View State. The regular CnP Transaction works fine though. Any idea? Thanks again for your support.

Good day!

You may have blacklisted yourself by testing in Production.

<DeclineFraud>true</DeclineFraud>

Please set the above node to False during testing so the fraud system does not trigger.

We need to review your IP and remove you from the blacklist database. Please change the node and do test transactions in TEST mode.

Please note that in TEST mode we don't check for fraud but when in production patterns are analyzed and the system may flag you if it thinks you are verifying credit cards.
