Pop up window when being in zoom which says that it is not possible to stablish a safe conection

Since today I have had a pop up window saying that it is not possible to stablish a safe connection with zoom . If I click on " open certificate " it appears the following" DigiCert Global G2 TLS RSA SHA256 2020 CA1 "error code 6: The Certificate from DigiCert Global G2 TLS RSA SHA256 2020 CA1 is not safe" This message is issue for *zoom.us , Organization: Zoom video Communications Inc.  Series Number: 06 E4 51 35 FO 63 AA C59B 1C 32

EE 46 C7 35 8 E . 

Issued by: DigiCert Global G2 TLS RSA SHA256 220 CA1  Organization: DigiCertInc

 

And if I open the browser I can connect but still the pop up window continues poping up. 

 

Last week when I logged it appeared that there was a new update, but I didn't update my app, could this be the reason of this popping up window today? 

 

My PC operating system is Windows 7. 

 

Thanks , I need someone to tell me what to do in order to be able to continue having my online meetings. 

 

Regards,

      Hi @aceenglish @Mauricio1977 @Massimiliano @nom234 @MTDarulHikmah, welcome to the community! This issue you are facing could be resolved by a couple of things:

       

      First, would suggest Uninstalling and reinstalling the Zoom application downloading the latest version of Zoom

       

      Second recommendation, I would verify the following firewall rules are in place for certification validation with Zoom. More information here

       

      The Zoom client 5.5.0 or later requires allowing the following URLs for certificate validation.

      Protocol Ports Source

      Destination
      HTTP 80 Zoom client crl3.digicert.com
      crl4.digicert.com
      ocsp.digicert.com
      crl.entrust.net
      certificates.godaddy.com
      crl.godaddy.com
      ocsp.godaddy.com
      certificates.starfieldtech.com
      crl.starfieldtech.com
      ocsp.starfieldtech.com

       

      Thirdly, after configuring firewall and reinstalling, this may need to be handled by our Zoom Support team, as it looks like they're gathering logs for similar issues if you're unable to configure firewall rules successfully. 

       

      Let me know if this helps!

        have same problem within domain environment on win10 machine

        if we try to log in using zoomacc(at)example.com at machine M and AD user domain\username - we get that error

        if we try to change AD user on same machine or try to login same AD user on other machine (same Zoom account) - we log in Zoom successfully

        already tried:

        • clearing %userprofile%\AppData\*\Zoom
        • reinstalling Zoom client

        I have the same problem since a few days and installing new certificates did not help, my firewall is unchanged and I can log in on the website. Is there any solution available apart from installing a new system?
