Live stream doesnt work
**Describe The Problem:**
I am not sure if it is bug or I just did mistake somewhere.
I have been trying to add my iGet cameras into the HB. Adding as itself worked pretty well, I have all my cameras in homebridge and homekit. Unfortunately I do have a weird problem - once I am connected to the home network I am not able to opet cameras and have a live stream...I keep getting errors like:

Once I am disconnected from my home network and try to connect from data or other network I am able to get the live stream without any problem
