@tommy  
I have checked my package.json and package-lock.json for maybe the 100th time now.

I’m certain that I have @zoomus/websk version “1.7.10” installed

but its still loading the below urls, which are of version 1.6.0 (i think):

[https://source.zoom.us/1.6.0/lib/av/5510\_audio.encode.wasm](https://source.zoom.us/1.6.0/lib/av/5510_audio.encode.wasm)  
[https://source.zoom.us/1.6.0/lib/av/5510\_video.decode.wasm](https://source.zoom.us/1.6.0/lib/av/5510_video.decode.wasm)

Can you please look into this ASAP.

Hi Tommy - When we accessed the site using internal IP over a VPN connection , we faced this(wasm error) issue.Yesterday I accessed the site using external IP (internet) without using VPN connection and we longer face the ‘WASM error’.However we are facing this now.

 ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/d/d9d3cba1cfc12edaa4d4aa295fc2c5453f550bd3.png) .

I am following this thread ‘[Your browser doesn't support using computer's Audio device, please upgrade your browser to the latest version](https://devforum.zoom.us/t/your-browser-doesnt-support-using-computers-audio-device-please-upgrade-your-browser-to-the-latest-version/22872/28)’ to see if it is resolved…

Meanwhile will try to serve the site in HTTPS to see if that solves the issue.

Thanks,Lidia

Hey @tommy,

I am also getting the same sort of error while joining the meeting from web sdk.  
This is hosted on https:// and you can see the console error and it shows few files are not able to locate in the directory.

Hey @ankitladhania,

Can you share a github repo with the issue so I can debug it locally?

Or please share your Web SDK code snippets here.

Thanks,  
Tommy

Hey @vishwajeetbhosale, @dharminder,

Do you have a firewall in place that could be blocking loading the Web SDK resources?

Thanks,  
Tommy

Hey @tommy,

I have tried disabling firewall also but still it’s not working for me. I have provided you a link for published version so can you try hosting that so that it can be checked if there is any issue with published version because if you see the console error then you will find out that there are few files for which error 404 is showing, are not available in node\_modules folder.

Infact on my local system firewall is on and this is working fine so why not on cloud server.

Please check this issue on urgent basis.

Hey @tommy,

I was able to resolve this issue by adding the following lines to the webconfig file :

![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/a/a7723fe2776bd438725d3dc19a7ace0e38121a1b.png)

My application was hosted on IIS and IIS was not allowing .wasm file extension to access.

Thanks for your support and quick responses.

@tommy,

I’m facing the same issue with my second account which is a Pro Licensed account.

Regarding network and Firewall, it is working fine for one of my react app but for the other, it is not and giving me error as access denied, status code 403.

Here is the snapshot for the same

 ![WasmError](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/b/b8053d0744c8d6e67943af69707d5f03dd625834.png)

Just to be more specific - my both react app shares the same code for zoom integration, generate sign and join & create meeting.

Below is the code for JoinMeeting Component.

```
    async start() {
    const signature = this.state.sign;
    const meetConfig = {
      apiKey: process.env.REACT_APP_API_KEY,
      meetingNumber: this.state.meeting_number,
      leaveUrl: "http://localhost:3000/Dashboard",
      userName: this.state.patientName,
      passWord: this.state.meeting_pwd, // if required
      role: 0, // 1 for host; 0 for attendee or webinar
      signature,
    };

    console.log("Meeting-COnfig", meetConfig);
    ZoomMtg.init({
      leaveUrl: meetConfig.leaveUrl,
      success() {
        console.log("Meeting-Number", meetConfig);
        ZoomMtg.join({
          meetingNumber: meetConfig.meetingNumber,
          userName: meetConfig.userName,
          signature: signature,
          apiKey: meetConfig.apiKey,
          passWord: meetConfig.passWord,
          success: function () {
            console.log("joining meeting success");
          },
          error: function (res) {
            console.log("Error Joining", res);
          },
        });
      },
      error: function (res) {
        console.log("Error Init", res);
      },
    });
  }

  async generateSign() {
    const response = await Api().post(`${config.API_URL}/gen-zoom-sign`, {
      meetingNumber: this.props.patientState.meetingCredentials.meetingNumber
    });
    return response.success;
  }

  async handleClick() {
    const sign = await this.generateSign();
    console.log('sign', sign);
    this.setState({
      ...this.state,
      sign: sign.sign
    })
    this.start();
  }

  async componentDidMount() {
    ZoomMtg.setZoomJSLib('https://source.zoom.us/1.7.8/lib', '/av');
    ZoomMtg.preLoadWasm();
    ZoomMtg.prepareJssdk();
    setTimeout(() => this.handleClick(), 1000);

```

}

Any suggestions here!!

Thanks,  
Vishant
