I have made simple example of mediasoup that can communicate with video and audio. I have checked that example works well in local. But when I put my example on deploy server, `DOMException: Failed to execute 'setRemoteDescription' on 'RTCPeerConnection': Failed to parse SessionDescription. a= Invalid SDP line.` occurs. I have looked many post in this channel and github. But there is no method to solve this problem.
