Ok so I am doing tutorials on webRTC and I've been using the following two tutorials to help me. 

[Sitepoint tutorial](https://www.sitepoint.com/webrtc-video-chat-application-simplewebrtc/) and [Scotch tutorial](https://scotch.io/tutorials/build-a-video-chat-service-with-javascript-webrtc-and-okta)

First thing to note, for the first tutorial even with the source code cloned from github here: 

> 
> <https://github.com/sitepoint-editors/simplewebrtc-messenger.git>

when I deploy the app on Now.sh it works but I am unable to join different users.

**TLDR;**

Here is [My Deployed App](https://simplewebrtc-app-lsjwsabgcv.now.sh/). When I try to join a remote connection I get this error

> 
> Uncaught DOMException: Failed to construct 'RTCPeerConnection': 'stun.l.google.com' is not one of the supported URL schemes 'stun', 'turn' or 'turns'.
>

Here is the [source code

```js
