Hi there! I’ve been playing around and got stuck. Both clients receive remote stream URLs, but the RCTViews are black. I found some logs, they say

> java.lang.RuntimeException: Catalyst Instance has already disappeared: requested by WebSocketModule

I put the full log here on [Pastebin](https://pastebin.com/RD5paaEW)

I would appreciate any help! Thanks!

Edit: I use Android devices, tried on real devices and real + emulator.

Nevermind, I took react-native-webrtc-minimal, modified it to support signaling server, and now it works like a charm!

@stuntingbrain, Brother, can you please help that why `onicecandidate` event is not firing? I am very close to it but for this, I can’t see the remote stream. I also modified react-native-webrtc-minimal to support the signaling server. Thanks in advance.

Hi! You might need to check if you’re setting local and remote SDP right. I put some code snippets here on [Pastebin](https://pastebin.com/q5nrQu34)

I used a lot of code from this [repo](https://github.com/shanet/WebRTC-Example). It is for the web, so it needs some modifications to make it work here in React Native(check the link above).

Good luck!

Thank you brother. Though I was setting up local and remote SDP correctly, it was not working. Probably the repo will help me. Thanks again.
