WPMU DEV API cURL SSL error

HI. I am continually receiving the same error message with my wpmudev api "cURL error 51: SSL: no alternative certificate subject name matches target host name 'premium.wpmudev.org'".

Host says that it's fine on their end and they stated, For information, this is not an issue with your server or firewall - we have tested this from a different server as well for you and the destination server is not accepting the SSL connection or is not using a supported cipher (ie out of date and insecure therefore not appropriate for a connection)?
