Skype for Business Edge Server reset connection

I ran in to a problem with a new Skype for Business server 2015 Edge installation. I was not able to connect to the sip.domain.com from a webbrowser. The browser finds the server but the server closes the connection (RESET). Therefore clients cannot log in at all.

So i fired up wireshark on the Edge server. I see my IP connecting to the Edge external interface, but it will give the message: “Reset: Set”
