Firewall settings for app

Hi, I have a ring doorbell working properly, but the Ring App (both win10 and android) does not show live video when connected thru my company network. It works either by connecting to another wifi, mobile dats or by using a vpn. I can access my recorded videos from the cloud, for example the recording of a live video from a few minutes ago, but not the live stream when sombody rings the bell. I guess it may be due to some ports clised or another firewall setting. Any help would be appreciated.
