Why ICE Error 1004 :

Sometimes because of network or stun server doesn’t provide the ICE candidate to webrtc call between freeswitch in the sdp offer and it wait for around 5 seconds for ICE candidate and if it doesn’t get any ICE candidate which is responsible to transmit the media stream because of this it fails to establish a ice connection and this cause to terminate the audio connection between server and client and finally you see – “Failure on call (reason=ICE error) error 1004”.

Another Reason could be your current server doesn’t support the ipv6 and freeswitch doesn support both ipv4 and well as ipv6 and when it try to make connection via ipv6 it get failed. Before checking any other solution first make sure you have correctly SSL is installed.
