    Dear jpat, Allow Online Meetings and Remote access tool category and test whether it is getting connected or not

    Dear Aboonaim Golandaz,

    too bad all of this is not allow in policy. How can we just bypass only for zoom meeting?

    Dear Jpat, I think we dont have applications for zoom meeting. Then we need to allow url of zoom in order to work.

    GET https://52.7.98.101/meeting/__get__?id=4AA270F3-A350-0747-1C89-41053C118D8C&session_id=4A786D7C-E485-BF9D-8F29-AD358BB520A7&post=0 RDNS lookup was restricted User-Agent: Mozilla/5.0 Zoom.App user: name=" " realm=  authentication status='none' authorization status='none' EXCEPTION(ssl_domain_invalid): Request could not be handled

    this could be the reason?

    Hello jpat,

     

    If you set destination domain for ZOOM application already, I think you should disable SSL detection for this application and test again. Because this error maybe ZOOM application using unnormal SSL encription.

    Pls. keep the PCAP file for make sure that or using action detect_protocol(no) on policy.

    The original question was to make Zoom work, so you would allow the resources listed by Zoom in that link. Are you trying to allow in a default deny environment, or something else?

    You can try the settings listed for Webex in here. You can see that the Zoom link is noted at the bottom.

    Hi Robert

     

    We have created a no authentication and no ssl decryption on the url domain of apple and zoom. Our main issue is that we are getting error 5003 on zoom application when using macbook behind the proxysg. But the application of zoom is working well when we use it on windows OS

     

     

    Thanks

    Hi,
    Did you refer below link from zoom

    https://support.zoom.us/hc/en-us/articles/201362683-Network-Firewall-or-Proxy-Server-Settings-for-Zoom

    You may need to disable both SSL validation and interception as well.

    Kind regards,
    Ruranga

    Hi Ruranga,

     

    We sent a no authentication and disable ssl interception policy for zoom.us, cloudfront.net on the link from zoom and to the domain apple we didn't include the IP address. Also do you have procedure on how to disable SSL validation on proxysg I can't search any KB regarding the procedure.

     

    Thanks
