**Meeting SDK Type and Version**  
**zoom-sdk-ios-6.0.12.15920 and zoom-sdk-android-6.1.0.22534**

**Description**

I updated (iOS and Android) SDK versions to the latest.  
I followed [Meeting SDK Auth](https://developers.zoom.us/docs/meeting-sdk/auth/) link to generate JWT Token which is mandatory for zoom initialisation

In my app there are mainly two methods for meeting and joining.

1. ZoomUs.initialize({  
jwtToken: jwttoken,  
iosAppGroupId: ‘[group.com.tautmore.org](http://group.com.tautmore.org)’,  
iosScreenShareExtensionId: ‘com.tautmore.org.ScreenShare’,  
})

2. const startMeeting = async () =\> {  
try {  
const joinMeetingResult = await ZoomUs.joinMeeting({  
autoConnectAudio: true,  
userName: `UserName,  
meetingNumber: 123456789,  
password: ‘B3NqhAVw00BY3q0hKevjOWzRVXUQm6.1’ || ‘’,  
noMeetingErrorMessage: true, // Set this to be able to show Alert.alert  
});  
console.log({ startMeetingResult });  
} catch (e) {  
Alert.alert(‘Error’, ‘Could not execute startMeeting’);  
console.error(‘ERR’, e);  
}  
};

After executing the app I am still getting errors like ( ZoomUs.initialize=\> ', [Error: Error: 11])  
Please help to fix the [Error: Error: 11] and generate JWT Token which is mandatory for Meeting SDK initialization.

**Error?**

1. First Time:  
I tried all possible ways but getting two type of issues  
'ZoomUs.initialize=\> ', [Error: Error: 11]

2. Send time:  
@“Already initialize Zoom SDK successfully.”

Current JWT Token:  
“eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzZGtLZXkiOiJIUzI1NiIsImFwcEtleSI6IkpXVCIsIm1uIjoiODE4MzkyMDQwMTAiLCJyb2xlIjowLCJpYXQiOjE3MjA1MTE3NzcsImV4cCI6MTcyMTIzMTc3NywidG9rZW5FeHAiOjE3MjEyMzE3Nzd9.MBs-wQ3k\_4HtJ0aHu4CBV2eM\_VME\_YuVAq\_97BPpsiE”

**Troubleshooting Routes**  
I have also tried to run with the sample app(iOS and Android) provided in SDK but found the same error.

Please provide the solution for an Error.

thanks.

@sai1

your sdkKey and appKey are not correct. You need to put in the client ID.

iat and exp are also too far apart, they can only be a maximum of 2 days differences from iat and exp.
