This error is typically a result of your server not being configured properly for https (SSL) and so is not able to connect securely to our API.
If it’s simply that your server isn’t setup with an SSL certificate, then the fix might be to simply toggle off the “Certificate Verification” option in the Settings tab of WP Migrate DB Pro.
If your server isn’t configured to support secure connections at all, we recommend updating it. If you are on XAMPP, take a look at these instructions.
As a last resort, you can instruct WP Migrate DB Pro to use insecure http (non-SSL) by adding the following to your site’s wp-config.php:
define( 'DBRAINS_API_BASE', 'http://api.deliciousbrains.com' );
