Video is not streaming while the client device is outside of the home network
I noticed that while connecting from outside of home network I still get the thumbnail, but the video is not streaming. The client device is trying to connect for some time and then gives up. It looks like the ffmgep process is actually starting on the hombridge side, but for some reason it is not getting to the client device:

```
  410 ?        Ssl    9:11 homebridge

```
If the client device is located in the home network it works as expected. At the same time, other cameras (with native HomeKit support) work just fine in either case.
Is it just my experience?
