Another 10DLC question - Upstream CNP declined without any explanation

[BDTS]

I received the SMS campaign decline notice, italicized text below. As you can see there's no explanation. Does anyone have any suggestions/ideas? I mean, I can't fix it if I don't know what is wrong with it. 

Your SMS campaign has not been provisioned because of the following reason, Upstream CNP declined sharing request for campaign C8YLDJF. Explanation: C8YLDJF.

The rest of the email are the links to Best Practices and other articles.
