Please contact your host and ask them to set up a server-level Root Certificate Authority (cacert.pem) file accessible to the PHP cURL module. If the first level of support doesn't understand that request please tell them that Nicholas from Akeeba Backup asked you to tell them to convey this request to Nikolai and Daniel. If Nikolai or Daniel have a question they know how to get in touch with me :)
