I received the error message when trying to login:
Your server had a problem connecting to WPMU DEV: "GnuTLS recv error (-9): A TLS packet with unexpected length was received.". Please try again.
If this problem continues, please contact your host with this error message and ask:
"Is php on my server properly configured to be able to contact https://premium.wpmudev.org/api/dashboard/v1/ with a POST HTTP request via fsockopen or CURL?"
I spoke with the hosting company and they said the connection to be made via a proxy server - https://premium.wpmudev.org/forums/forum/support#question
Are you able to help with this?
