Hello again, i have a developper license. I am getting this error after having installed a StreamLock certificate. About the MediaCp, is there any free offer for development. This is the error in the console: WebSocket connection to ‘wss://192.168.56.1:8880/webrtc-session.json’ failed: Error in connection establishment: net::ERR\_CERT\_COMMON\_NAME\_INVALID ---

That error can be triggered when you don’t have the correct port configured. Check that you have port 443 configured properly: Sometimes people have this WebRTC HTTP Provider in HostPort 1935 and it should only be in HostPort 443 ( Make sure it’s the 2nd to last entry just above HTTPServerVersion: ```auto com.wowza.wms.webrtc.http.HTTPWebRTCExchangeSessionInfo *webrtc-session.json none ``` You will need to uncomment HostPort 443 as that will be needed for SSL streaming for WebRTC. Save and restart your Wowza Server for changes to take effect. ---

I’ve found this issue when I did not configure my certificate. Have you followed these steps in the Configuring Wowza Streaming Engine to use your StreamLock certificate? [https://www.wowza.com/docs/how-to-get-ssl-certificates-from-the-streamlock-service](https://www.wowza.com/docs/how-to-get-ssl-certificates-from-the-streamlock-service) ---

At this point, we need a support ticket from you to view your complete configuration. There are too many variables involved in a WebRTC workflow and we can’t debug in the forums without full access to your files. You can [submit one here](https://www.wowza.com/support/open-ticket) and our WebRTC engineers will walk you through the setup after they find the error. ---

Using a streamlock certificate, your SDP url should look like the following - wss://{certificate\_name}.streamlock.net/webrtc-session.json where you replace {certificate\_name} with your streamlock certificate name (typically a series of numbers and letters). ---

I have edited your streamlock certificate to include X’s. You were sharing your private SSL information that is supposed to be kept private to protect your content. ---
