Companion Login Failed Error Message

I use PocketCloud Pro premium for quite a while now. But since the last update the companion doesn't want to configure the auto discovery. Everything works fine like configuring firewall, password etc just the last "autodiscovery option" doesn't work (on my ipad the login with my gmail account works fine). 

Reinstalled the app multiple times and used another gmail adress but without any succes. What is the problem cause I want to be able to use the app again....!

Looking for a quick reply since I need to use it!
