Stream is black on certain versions of IOS

Hi, we have integrated the Zoom WebSDK into our platform and this is working well on most devices, however on certain versions of Mac there is just a black screen. We have noticed that there is a 403 warning which turns into an error on certain versions of IOS that could be causing this.

The error message displayed is:
Failed to load resource: the server responded with a status of 403 (). net::ERR_HTTP_RESPONSE_CODE_FAILURE

Which version?

Device (please complete the following information):
Devices this is happening on:
MacBook Air 2018
MacOS Catalina 10.15.13
IPad Pro 3rd generation, Software: 13.4.1

Additional context
This looks to be a warning on other browsers, but an error on those Mac devices. It works on some Macs but not on others.

Code for reference:

			ZoomMtg.setZoomJSLib('', '/av');

			function joinWebinar() {
				var meetConfig = {
					apiKey: '**********',
					meetingNumber: ***,
					leaveUrl: '/webinars/zoom/meeting-ended.php?id=**',
					userName: 'user_name',
					userEmail: 'user_email',
					passWord: 'user_pw',

			fetch("/webinars/zoom/generateSignature.php", {
			        method: 'POST',
				body: JSON.stringify(meetConfig)
			.then(result => result.text())
			.then(response => {
					leaveUrl: meetConfig.leaveUrl,
					isSupportAV: true,
					success: function () {
							meetingNumber: meetConfig.meetingNumber,
							userName: meetConfig.userName,
							signature: response,
							apiKey: meetConfig.apiKey,
							userEmail: meetConfig.userEmail,
							passWord: meetConfig.passWord,
							success: function(res){
							//console.log('join meeting success');
							error: function(res) {
setInterval(function() {
// every 10 seconds
$.post( '/webinars/zoom/userTimeUpdate.php', { booking: 1 } );
}, 10000);
let timerVar = setInterval(countTimer, 1000);
let currentSeconds = document.getElementById("current-seconds").value > 0 ? document.getElementById("current-seconds").value : 0;
function countTimer() {
	let hour = Math.floor(currentSeconds /3600);
	let minute = Math.floor((currentSeconds - hour*3600)/60);
	let seconds = currentSeconds - (hour*3600 + minute*60);
	if(hour < 10) { hour = "0"+hour; }						
	if(minute < 10) { minute = "0"+minute; }						
	if(seconds < 10) { seconds = "0"+seconds; }
	document.getElementById("time").innerHTML = hour + ":" + minute + ":" + seconds;

Is there any update on this?

Hey @robert.dyas,

Thank you for reaching out to the Zoom Developer Forum. With version 1.8.5, there was a required update in order to allow the use of the new encryption standard that we implemented. You can find more information on this in the following forum post:

Please try updating to the latest version (1.9.0) and let us know if that resolves your issues.

This is a browser error indicating that it is unable to find files that can help with debugging and development. It doesn’t affect the functionality of the Web SDK

For future reference, we have a queue of forum posts that is chronologically sorted by the last response. When you respond to a forum post for an update, it resets your place in the queue and can cause delays in getting a response.
