*I was able to fix this issue - through contacting them by email. It worked on my Mac. Hope this helps someone.

*Open the Zoom desktop application.

Select zoom.us at the top of your screen and select Uninstall Zoom.
Select OK to confirm uninstalling the Zoom desktop application and all of its components.
Restart your Mac
Reinstall Zoom via zoom.us/support/download

I just started seeing this error today. The Zoom error (unable to establish secure connection to zoom) is referencing a certificate generated by our development system for a nonexistent domain for use internally and is completely unrelated to Zoom.

The error banner keeps popping up and there's no apparent way to suppress it.

I had the same problem. I resolved the issue by going to "Add/Remove Programs" searching for Zoom, and clicking uninstall. After that the message boxes stopped popping up and I could get on with my work.

The Zoom error banner seems to only display when docker containers are running hosting services on HTTPS tcp/443 serving that certificate on localhost.

Hi All,

I am able to fix this by login to Zoom online portal.

Under profile setting look for Calendar and Contacts Integration. Deleted the exiting integration setting and configured as per my company stand again by choosing O365 option.

I was having the same problem, and I changed my browser settings to always use secure connections (in Google Chrome go to Settings -> Privacy and security -> Security -> Advanced -> Always use secure connections) and it apparently solve the problem. Hope it helps.

This just started today. I have tried every suggestion on this thread and nothing is working. I am on a Mac and does not matter if I use Chrome or desktop app. This is becoming debilitating.

This also started for me last night and is very annoying! Won't go away. I have no settings with my organization for my calendar and contacts integration therefore have nothing to reset. Tried everything else here too and nothing seems to work.

This also started for me yesterday and none of the above solutions have worked to resolve it (updates, time/date, calendar sync, etc.). Something must have changed on Zoom's end, right? This question needs revisiting!

I also have had this issue since the beginning of 2023 and it's causing disruption to my meetings. I'd like a solution please zoom. It can't be an unsecured connection when I'm conducting zoom meetings just fine.

Additional info: We have 3 macbook pros in the office. All on the same network. Tried both browser and desktop app to use Zoom. Only 1 computer has this issue. I have tried hard-wired to ethernet and wifi. I have disabled Avast. I have tried all solutions mentioned in the thread. The problem computer is on the latest Zoom version 5.13.4 and OS Monterey. 2 with no problem are on 5.12.9 and OS Monterey and 5.12.2 and OS Big Sur. I do not see a way on Zoom.us to download an older version of the software to test. The first I noticed the issue began January 10, 2023 8AM ET. Everything was fine as of January 9 4PM ET. Does anyone from Zoom ever check these threads?
