javascript - Vuzix M100 and Webrtc Error: connect failed: EHOSTUNREACH (No route to host) -
here szenario want reach:
i want develop 2 way remote video conference vuzix m100 (android api 15) , google chrome browser / alternatively firefox. in order reach connection i'm using webrtc , node.js server websockets enable lookup of 2 clients.
the problem i'm facing if connect 2 chrome browser clients in detail android device (sony xperia z 3 compact) , deskop pc works perfect. if try connect vuzix on browser i'm getting error there no route host.
