Donation Rejected due to to AVS mismatch

I just upgraded from 3.5 to 4.3. Getting the following message:
Your donation was failure
Reason
The transaction has been declined because of an AVS mismatch. The address provided does not match billing address of cardholder.

Have checked declines in Authorize.net but none there so appears info is not getting to Authorize.net. Using plugin method with JDFORM in article content. Running Joomla 3.6.4.

My customer is getting unrestful
