This sequence of code causes an exception:

```
  this.client = ZoomVideo.createClient();

 const initRes = await this.client.init(
    'en-US',
    'http://192.168.1.172:3333/@zoomus/instantsdk/dist/lib'
  );

```

However the same call made to/using localhost, on the computer assigned to IP  
192.168.1.172, is working just fine.

And the files in the SDK are reachable when that IP url is entered in a browser address line. (e.g. http:// 192.168.1.172:3333/ @zoomus/instantsdk/dist/lib/webim.min.js - minus spaces, which I just put in to prevent this editor from making the URL clickable - returns the minified JS file specified)

What may be the issue here?

This is the console error that we’re getting:

```

Hey @brianWD

Thanks for sharing your questions.

According to the specification of [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices), it only can be accessible in a [secure context](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts). So you can use `http://localhost` or `https://` to serve the assets.

Thanks  
Vic
