That specific message means a mismatch in the name on the certifiate and the address you are using in the URL. The common name of the certificate should match your DNS name for the controller. For example. CN=aruba-master.domain.com. URL: https://aruba-master.domain.com:4343
Can you confirm/compare the URL and the Common Name on the certificate (the Issued to: entry)?
You'll sometimes get one of the following:
The security certificate presented by this website was not issued by a trusted certificate authority. = Trust Issue
The security certificate presented by this website was issued for a different website's address. = Name mismatch
