[URGENT] Zoom redirect https join meeting request to http and blocked by the browser

We use iframe to embed zoom web client on our web page. Today all the meeting request https://zoom.us/j/meeting_id are re-directed to http://zoom.us/j/meeting_id, and therefore blocked by the browser. When try to join the meeting, it only shows a blank page.

Smartphone (please complete the following information):

  • Browser: Tested on chrome and safari

Additional context
It suddenly happened today, previously it works fine.


Urgent for me too. This bug (or change?) disjointed an entire elearning website.

Works only in Firefox.
Please fix it asap.

FWIW I also reported this here: Web client has stopped working when embedded in an IFRAME and I’ve seen several other reports. Though none with a reply. We ended up scrambling to use the WebSDK instead as that was the only fix we could find.


Try to use another join url like this
<iframe src=“https://zoom.us/wc/join/11111111111” sandbox=“allow-same-origin allow-forms allow-scripts” allowfullscreen=“allowfullscreen”></iframe>

Hey @flippyhead, @xinxin, @elearningevolve, @pavel.p, @gbtondo,

For the best experience embedding Zoom into a website, please use the Web SDK instead of putting Zoom meeting links in an iFrame.


Thanks @tommy. Does Wed SDK need PRO account?

Hey @xinxin,

Yes, the Web SDK requires a pro account.


Hi Team,

Using the below iframe (the same for any ID) and it just doesn’t work in Safari. Other browsers are fine:


[blocked] The page at https://zoom.us/wc/join/98815756866 was not allowed to display insecure content from http://zoom.us/wc/join/98815756866?tk=&prefer=0&track_id=&meeting_result=&imf_code=&wpk=&_x_zm_rtaid=S0p4TSGPQguRXGmIpH6UFw.1588954022978.fad827a366de57e55ac38c3b75f321a0&_x_zm_rhtaid=751.

Please advise @tommy


Hi @vadim.plakhtyr,

Yes, Safari has heavier restrictions on iframes. Can you make sure to include https in your url to see if that works?

Yeah, we did make sure. A lot of people have the same error though. Seems like the issue is on your end guys, since the error says that https:// version of your page cannot display insecure content from “the same page but http:// ?”

Sounds more like an internal issue to me. Could you please investigate this further?

Hey @vadim.plakhtyr,

Embedding the Zoom Web Client in an iFrame is currently not supported and does have issues.

Please use the Web SDK to embed Zoom meetings / webinars into your website.


@tommy before you forward people to use the SDK, please be so kind as to look at this thread:

Thanks @mystery,

We will take a look.
