403 Forbidden on WPMU DEV Dashboard Login

I'm seeing odd behavior on all of my installs, they have reverted to non-pro but give no specific error. I also can't update them to the latest version.
If I log out of the WPMU DEV Dashboard plugin I get this error when i try to log back in:
"Your server had a problem connecting to WPMU DEV: "HTTP Error: 403 "Forbidden"". Please try again."

I have spoken to my host and they mentioned that they aren't blocking any post requests (outbound connection). Please advice.
