@nsaxena I’m thinking it might be a code issue and not a signature issue.

I can’t verify it right now and the signature might probably expire before I can get to a workstation.

In your screenshot, Could you share the x-zm-tracking from the headers?
It is from the same URI info?meeting……….

32

@nsaxena updates, this meeting number is not a valid number

@chunsiong.zoom , I am sharing you new detail, also sharing z-trackingid, It is not code issue, It was working perfectly with OLD SDK earlier , please review and let me know

@nsaxena ,

thanks for the tracking ID.
It appears there is something wrong with your IAT
It is appears to be in the future, hence the first few times when attempting to join throws the invalid signature error.

At time of joining, the IAT in your signature is 5 seconds in the future.

You might want to sync your machine’s time, or manually set IAT to be 5 mins before “current time”

@chunsiong.zoom ,
Thanks for letting me know new finding, I am checking with our IT team for application server time, it will take some time, I will connect you or will update you soon.

Regards, nikhil

36

@chunsiong.zoom , Thank you so much for your kind support with patience.

I reduced my time 5 minute. And then I was facing issue JsMediaSDK_Instance is not defined , so for resolving this I set refrence .1.6/lib/av/js_media.min.js file.

And I am able to launch and join meeting after making these changes. Here is screenshot
