username_0: <!-- You must use the issue template below when submitting a bug -->

**Describe The Bug:**
After switching to new homeridge raspbian image, I get a No route to host error when trying to view a camera. This worked in HOOBS before I switched. I've tried connecting with the same ffmpeg command line in the terminal of the homebridge pi and i don't get the same 'no route to host' error, so i don't think it's a network issue (unless there's something weird going on in the new homebridge raspbian image)

**To Reproduce:**
Open the camera in home app

**Expected behavior:**
The camera should be visible in the home app

**Logs:**

<issue_comment>username_1: ifconfig and check your gateway on the server... it doesnt know where that network is... probably bad DHCP or you assigned the IP wrong on the server.<issue_closed>
