Unable to establish secure connection with Zoom

[Gagan]

Hi Team,

One of my user in office facing issue while joining Zoom meeting "Unable to establish secure connection with Zoom"

Screen shot is attached. Any idea what we can do in this case. Have already tried reinstalling ZOOM app and User had tried different internet service provider for connecting Zoom meetings

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 solved this by doing everything I saw listed in this thread then resetting. So I first went into the calendar integration and took it off of any calendar connection. Then I deleted Zoom and reinstalled it. Then I restarted my computer. That was really frustrating, though.

I'm on a Mac.  This solution did not work for me.  I am an individual.  I tried to connect via google, but google blocked the attempt to connect.

Shortly after I reported the problem to zoom, I was asked by them to update my zoom room client.  It worked fine after that with no more error messages. (I had updated several times before that with no change.)  Are they using a laptop, phone, or a tablet?  I was having problems on my mac pro and not on my P.C.  If it is a tablet or a phone, there may be some issues not addressed. I've not heard of anyone still having this problem. 
If you are still having problems, report it to Zoom via Contact Us.  They were very responsive.
