Steinberg Download Assistant "can't connect to the server"

Hi! I’ve encountered this problem with “Steinberg Download Assistant”, as soon as I open the program it says that “it can’t establish a connection to the server” and to check my internet, which is working though…
I’ve update Java since I’ve seen there are files working with and allowed the application through the Firewall but nothing changed. I don’t know what to do next.
Hope someone can help. Thanks!

It might be that your installed version of Steinberg Download Assistant is old, and it’s trying but failing to update itself. Please try reinstalling the latest version from here and see if that allows you to progress further.
