Hey @vijayk.kannan,

What percentage of times does this happen?

Can you share a screenshot of the error?

Can you please share the signature of one of the meetings that has thrown that error?


This happens about 5% over 200 calls we do every day , here is the signature

Here is the one more meeting id which has this issue

More issues on this latest version

  • User cannot able to see their own video or image
  • Even if you allow camera or microphone on chrome still both has issues on using them

I am really like to talk to someone on the phone to sort out whats going please let me know

Hi @vijayk.kannan,

For the signature issue, make sure to use the system time and make sure the time syncs with world time.

  1. Generate a signature by ZoomMtg.generateSignature. - Example of syncing your machine time using window 10

Example for using Mac

  1. Generate a signature by customer web backend with sync server time.

We are currently investigation to see if there is a sync issue on our end as well. We’ll follow up as soon as we’re done looking into it.

Can you post a screenshot of what they see and the developer console errors we want to make sure it’s not a config issue.



Thanks for your information , I have raised a ticket about the audio / video issue but still there was no answer about why my own video image was taken out by this release 1.7.2

Hi to all, the issue is with ZoomMtg.generateSignature that method is failing for some reason, if you generate the signature using your own backend as some examples shows It works

Thanks for following up @JuanLopez. You are correct, to generate signatures please use a backend service.

@vijayk.kannan - We need to details so that we can further investigate. Can you post a screenshot of the Video issues within the Web SDK along with a screenshot of the Developer console logs, so that we can see the errors?


Hi Micheael!!

I have this problem with several users, the question is, not everyone can update the time because they are over intranet and the time is the one of their local server. Is there a way to solve it without them having to change the time?

Hey @sandra-rosiles,

Make sure you are generating your Web SDK signature server side in UTC time and it should work.

Happy to hear you got it working! :slight_smile:


How? please!
What format do you use?


Infront of gmdate just use date(“Y-m-d\TH:i:s”,strtotime($post_time->format(“Y-m-d H:i:s”)));According to your country use timezone
