If I use a TURN server (coturn) with only a turns: scheme URL, and this TURN server use a valid Let’s Encrypt certificate, relay candidates are never generated. This is happening for both iOS and Android. If I use a GoDaddy certificate, candidates are generated.
Relay candidates with Let’s Encrypt certificate are properly generated in web browsers and also in Android WebView.
I tried to take a look into WebRTC source code and they are using here and there
tls_cert_verifier, but I didn’t find where it is generated (if any). In some other places it is just set to
This was already happening in other similar projects like cordova-plugin-iosrtc
Thanks in advance.
