Unable to establish a secure connection to zoom


The pop up message, "unable to establish a secure connection to zoom" has appeared repeatedly over 3 hours of meetings today.  Probably about every 10 seconds.  It is impossible to continue to use zoom if i cannot resolve this.  I have uninstalled it and re installed it, I have gone into calendars and contacts and tried to change things. 

Previous advice on the community said to delete existing calendars and integrity settings and reconfigure.  Can someone explain this.  Any help greatly appreciated.



I don't have an answer, but have the same issue (also started yesterday). Someone please advise!!!

I am having this same problem, since trying to run a class last night. It obscured my view and access to some participants.



My wife is experiencing the same problem on her Macbook Pro. We are supposed to start teaching a course tonight.



I am having the same problem today. The live chat person was not able to help.

Hoping someone figures this out soon!


I am having the same issue on my mac book pro. PLEASE HELP! Have tried all of the above


Same issue , started yesterday   - MacBook , have reinstalled but no change 😞


Ditto to all of this.  Same issue. 


I opened a ticket with Zoom on Jan 10 for this issue - here's the resolution from them that worked for me. I'm using a MacBook Pro running Monterey, so the instructions are specific to Mac. I would assume similar steps are needed for non-Mac users.


  1. Quit Zoom
  2. Go to Finder
  3. Click Go at the very top of your screen
  4. Hold the Options button down on your keyboard
  5. Click Library when it appears
  6. Open the Application Support folder
  7. Delete the folder
  8. Go to Applications and remove Zoom if it is still in there
  9. Reboot your MAC laptop
  10. Redownload Zoom to get the latest version and install it

Thank you.  This worked for me.  I really appreciate the explicit steps you included.

This worked for me. Thank you - it was driving me crazy for days!


SAME!  This began on 1/10/2023 out of the blue and occurs constantly while I am on my Apple laptop.  I've used for years on the same laptop without issue.  The best I can do it drag the notice off to the side.  THIS IS TERRIBLE!!!
