When I am at home or connected through my MiFi everything is OK, when I am connected through my jobs corporate firewall Messages app does not synchronize or can send or receive iMessage messages, although it's logged in just fine. My iPhone with the latest iOS 11 beta works fine though.
The funny thing is the Mac (Macbook Pro 13" touchbar), was also working fine until High Sierra beta 3, now with beta 4 it does not. Does anyone know if Apple changed the default ports? All my colleagues with MacOS Sierra are fine.
