Rate limits on joining meetings/webinars?

Further to this, is it not possible to put a descriptive error message so that we don’t have to guess and go back and forth like this for weeks? The error message does not tell us anything about what the issue is. Thanks.

Hey @developer-whova,

It depends on the host of the Meeting / Webinar.

Are you using the Web SDK to join the meeting / webinar or host it?

Thanks,
Tommy

Hey @ryan-sey,

First off, we are releasing better error messages in version 1.7.9, so stay tuned. :slight_smile:

It seems like this could be an issue with the Web SDK. I will share this with our Web SDK engineers and get back to you all. (CS-1944)

Thanks,
Tommy

Then this seems to be an issue on Zoom’s end: the limit does not seem to match the host’s plan, but the Web SDK plan. We do not use the Web SDK to host meetings, but to join the meeting.

From our observations, Zoom is enforcing some limit on the number of concurrent users of the Web SDK, even if those users are attending different meetings, and that the limit seems to sit around 300 users. For example, if 100 users attend meeting A, 100 users attend meeting B and 100 users attend meeting C, this limit will be reached.

It also seems that the limit applies based on the developer’s account plan, not based on the meeting host plan.
For example, the host plan can support 1,000+ attendees per meeting, but the Zoom Web SDK will only allow up to 300 attendees at a time across all meetings. Additionally, once the limit is reached, no meeting can be accessed, even if those hosted by different customers.

One final observation confirming this is that the meetings that could not be joined using the Web SDK while the limit was reached, could be joined using other means (e.g.: App SDK, Zoom Desktop Client, …).

Best.

Thanks for the additional info @simon.ninon!

We are looking into the issue and will provide you with updates.

Just to let you know, it seems it happened again today and affected multiple customers (at least 3) between 12:00 PM and 12:15 PM. For this one, I am not 100% sure it is the same issue because by the time our customer support caught it, it was resolved, but the symptoms are all the same (increase of number of users / load of the Web SDK causing join failure on all meetings across different customers).

Hey @simon.ninon,

We were able to reproduce the issue and are working to find the root cause.

Thanks for your patience,
Tommy

Great, thanks for the update!

Hey @tommy

We noticed that the upcoming SDK, 1.7.9, will implement “new rate limit”: https://marketplace.zoom.us/docs/guides/stay-up-to-date/upcoming-changes/web-sdk

Will this address our issue, or is it unrelated? If it does, is it possible to get more information regarding these new limits so that we can better understand what to expect?

Hey @simon.ninon,

The rate limit update is different from your issue. It is related to in meeting functions to prevent users from spam pressing buttons. For example, if someone calls the mute button over 10 time per second. The current rate limit is 5 p/s so we will disable the action.

Thanks,
Tommy

Hey @tommy , we seem to be experiencing a similar behavior to this as well, so I have been following this thread with curiosity, can you expand upon what the actual issue is that @simon.ninon and his team are facing?

Hey @travis.boswell,

I will update you once we know the root cause and are working on a solution. :slight_smile:

Stay tuned!

Thanks,
Tommy

Hey @tommy,

We are very near to running an event with 300+ participants through the WebSDK. I’ve just come across this thread and would like to confirm whether this is ongoing or resolved?

If it is ongoing, are there measures we can take to reduce the risk of this issue such as spreading our users across multiple JWT Apps, or using a different version of the SDK?

Thanks,
Alfie

Hey @alfieb,

We have not received any new reports about this issue. I am confirming with engineering to see if this is resolved. In the meantime please let me know if you run into this issue.

Thanks,
Tommy

Hey @tommy,

My company has many virtual events that run from July to December 2020.
And we use the Zoom Web SDK with 1000+ participant on website, but since July we are facing the same problem to join.

A brief description of our account:

One PRO Account has multiple users to manage.
2020-10-27-181249_394x331_scrot

=> Today, these 3 of 5 accounts run meeting parallel as hosts on the Zoom Apps.
=> attendees join from the website to 3 meetings ( with same API Key & API Secret JWT from PRO Account )
=> when the number of participants reached more than 300
=> an error will appear, but a few hour later can rejoin (this over and over again)

Error:

{
method: “join”,
status: false,
result: “No permission.”,
errorMessage: “Fail to join the meeting.”,
errorCode: 1
}

Which version ?
1.8.0

Additional
Also, 300 or 1000 license for web sdk limit ?

I’ve been following this thread ever since, but it seems unresolved until now.
We have many complain about this issue. How can we take to reduce the risk of this issue ?.

Sorry for my bad English :).

Thanks,
Waya

Hey @wayaragil,

Thanks for reporting this. Our Web SDK engineers are looking into this issue. In the meantime, if you still see the errors starting around 300 participants, I suggest using the Zoom App so you can have more participants join.

-Tommy

Thanks @tommy for your reply in advance.

I hope this problem is resolved soon, because the zoom web sdk is the main feature on our website. So, Zoom App is our last choice :slightly_smiling_face:.

@tommy @wayaragil Hi.
Are webinars still capped at 300 max attendees via Web Sdk, even if the hosts are running Zoom App?
