I am running Wowza locally on my MAC. I have a valid license. I download the WebRTC trial. I created a StreamLock certificate and made the necessary changes to the various configuration files. I also enabled the local Wowza http server. I am using the following SDP URL: wss://10.0.0.36:1935/webrtc-session.json The browser is not able to connect. When I try to publish I get the following error: WebSocket connection to ‘wss://10.0.0.36:1935/webrtc-session.json’ failed: Error in connection establishment: net::ERR\_SSL\_PROTOCOL\_ERROR 10.0.0.36 is the IP address of the machine and the IP address I used in creating the certificate. i tried using the certificate name as well. I tried without port also and got the following error: WebSocket connection to ‘wss://10.0.0.36/webrtc-session.json’ failed: Error in connection establishment: net::ERR\_CONNECTION\_REFUSED. Definitely need to use a port - look at what was listening on my machine and 1935 seems to be the only port I would use. What should the SDP URL be? Also do I need to configure a stream through the Wowza interface? Thanks, Tim McClure ---

Hello, You will not be adding port 1935 as that is for RTP streaming for WebRTC. Your SDP URL needs to look something like this: wss://5555555555.streamlock.net/webrtc-session.json If you use the “publish” example you will not need to create a stream. If you are having further issues, please open a [support case](https://www.wowza.com/support/open-ticket), along with the below folders for review: [install-dir]/conf [install-dir]/logs (only latest logs showing connection attempts is needed) [install-dir]/htdocs If you are not sure how to get this information please see the following tutorial.

If you mean custom SSL certificate, yes you can: [https://www.wowza.com/docs/how-to-request-an-ssl-certificate-from-a-certificate-authority](https://www.wowza.com/docs/how-to-request-an-ssl-certificate-from-a-certificate-authority) If you mean custom Websocket server, you’ll need to use Wowza’s version that can be overrided: [https://www.wowza.com/docs/control-access-to-webrtc-publishing-and-playback#enhance-webrtc-publishing-and-playback-security-with-a-custom-http-provider7](https://www.wowza.com/docs/control-access-to-webrtc-publishing-and-playback#enhance-webrtc-publishing-and-playback-security-with-a-custom-http-provider7)
