zoom doesn't log in on Mac and won't join a meeting

@CristhianM I would start with uninstalling and reinstalling Zoom to see if that resolves the issue. 

If it doesn't, try connecting from a different network altogether to see if it was an issue with the network you were initially connecting on.

I have already uninstalled and reinstalled zoom and it still doesn't work and I have tried with different networks altogether but the problem doesn't solves 

For what it's worth, I am experiencing exactly the same issues.  Zoom was working fine on my MacBook Pro until a few days ago, but it now fails to connect.  I have uninstalled and reinstalled the Zoom client, and tried this on both hard wired and wireless networks, but nothing works.

I had exactly the same problem and spent 10 hours with Apple Support and they could not fix it--it wasn't my laptop or connectivity. It's a problem with Zoom Client. There is a workaround. First, try connecting using Chrome rather than Safari. Second, when Zoom Client starts its spinning, move it to one side so you can see the brower window.  There is a link that says "Problem connecting with Zoom Client? Try connecting on your browser." If you don't see that link, click on "Launch Meeting" and the link should appear beneath. AND--let the Zoom Client finish its spinning so you can "report problem." I hope that if we keep reporting a problem with Zoom Client that Zoom will fix Zoom Client!

Mine has been doing the same for nearly a month and I'm fed up. I take online classes and it won't work.

There may be good news. I checked again last week and Zoom’s website has some new downloads that are Mac-specific. I’ve installed the version for my newest Mac and it’s a huge improvement (in that now I can get into the meeting). There are still some rough edges but it basically works. I haven’t updated zoom on my older laptop but will try soon . 

I have already uninstalled and reinstalled Zoom on my Mac, but the issue still persists. I also tried joining with different Wi-Fi networks, yet I keep getting the same connection error and can’t log in or join meetings.
