Ice4J: Ice State Failed on 4G network

903 views Asked by At

Does anyone know how to do the TURN portion of Ice4j? I've managed to code it so that it works when the phone is on WiFi, but not when its on the mobile network.

I'm sending agent info via TCP and then building the connection manually instead of using a signalling process. The TCP connection already works fine, so I don't think its the TCP issue. Maybe I'm building the agent wrong?

I know that you're supposed to use a TURN server if STUN doesn't work, and I provided a large list of public TURN servers, but I might be missing something. Maybe the packets aren't being sent out properly?

I realize now that your list of TURN servers seem to mostly actually be STUN servers (not sure about the first two). They should be added as STUN servers if anything:

 agent.addCandidateHarvester(
   new StunCandidateHarvester(
       new TransportAddress(
           InetAddress.getByName('stun.l.google.com'),
           19302,
           Transport.UDP)));
