Track contentHint unsupported
This means your browser does not support MediaTrack.contentHint property. The warning can be ignored.
ICE failed
This means ICE is not working properly. Please read here how WebRTC connection is establishing. You should check if server media ports are available for the client to connect: Port routing checking. Ports may be locked by the clients ISP for example, in this case try to use TURN to bypass.
