Original GitHub issue: https://github.com/games-on-whales/wolf/issues/116

This has been reported in Discord, the short version is as follows:

LAN IP: 192.168.1.X
Wireguard IP: 172.17.0.Y

Moonlight was reaching Wolf via 192.168 and Wolf was sending back the video and audio stream over 172.17, as a security measure Moonlight will reject that because it comes from an unknown IP.

Snippet from the logs:

DEBUG | 172.17.0.2 [GET] HTTPS://192.168.1.20/appasset
DEBUG | 172.17.0.2 [GET] HTTPS://192.168.1.20/serverinfo
DEBUG | 172.17.0.2 [GET] HTTPS://192.168.1.20/launch
...
DEBUG | Starting video pipeline: 
...
udpsink bind-port=48100 host=172.17.0.2 port=51928 sync=true

Manually setting the env variable WOLF_INTERNAL_IP fixes it but I think we can do better here and automatically match the IP from the HTTPS endpoints when setting our IP for the Moonlight session.
