SSL problem during Woocommerce Import

When trying to do a product import on my Local site from the remote site (https://shop.ballantynestrong.com) using Woocommerce’s built-in importer/exporter, I get an error for any product that has images that reads:

Error getting remote image https://shop.ballantynestrong.com/wp-content/uploads/2015/06/DSC_1776-2.jpg. Error: cURL error 60: SSL certificate problem: unable to get local issuer certificate.

There are 143 products that don’t import because of these SSL errors.

My local site is using Local’s OpenSSL cert and seems to be running fine via https.

Any idea how I can get around this issue?
