    @不明なエラー I cannot find any Zoom error with that code.  What were you doing when you encountered the error, and are you able to reproduce it?

    I was trying to sign in to the zoom app from my coworking space. However, I got that error code and a message that said "Unable to connect to network. Please check your network connection and try again.

    Are you running Zoom locally on your machine, or is it on a virtual machine elsewhere?  You are obviously able to connect to the internet to be posting these message, so I am trying to figure out what network it is not connecting to.

    I am connected to the network via the co-working space's Wi-Fi, no problems with network connectivity other than zoom. google meet is also available. In that coworking space, I can connect to zoom when I use the Wi-Fi at Carrie's office with my iPhone desserting. Obviously, there seems to be a problem between the coworking space's Wi-Fi and the zoom connection. However, other users of the coworking space can use zoom without any problem. Is it a problem with my network settings? But I don't know the cause.

    Are you using a VPN?  The only time I have seen anything like this is if the ports (or some of the ports) are blocked to Zoom, but that is usually found when you are working with a corporate firewall.  That can be inconsistent if only some of the ports are blocked since 1 person can use a different port than the next person, so 1 will get in and the other might not.  Have you always had the problem at this location, or is this new or intermittent?

    Hello @KishoreR and @不明なエラー,

    Could you please run the CleanZoom application provided HERE, and then restart your computer when it's finished?

    Once you are done restarting, please visit this link: https://zoom.us/support/download this will automatically download the newest version for you.

    Please install this version once it is downloaded.

    Checking to see if I can find anyone who has seen that error in the past since I can find no reference to it.

    I am having this same issue with the Zoom Workplace app that I downloaded on a new iPad. I have the app on my phone and MacBook, with no issues, but I cannot login with my iPad.

    I am having this same issue. I tried updating the zoom app and restarting my computer, but the problem is the same. I can log on to zoom through safari, but once I try to enter a meeting or start a meeting, it goes to Zoom Workplace and asks for my email and password. When I type those in, it tells me, "Unable to connect to network. Please check your network connection and try again" and it gives me an error code of 5456000. I don't have this problem when logging in from my phone. Please help!

    Are you using your laptop in the office?  It sounds like the ports to Zoom are blocked, and so it is preventing you from connecting over the network.

    Yes, from my laptop. I checked my security settings under Safari, and pop up windows have been allowed for zoom. So, I'm not sure what is creating the problem.

    I am having the same issue. Mac OS Sequoia 15.5 Zoom Version 6.4.12. 
    This was working a few days ago. No VPN. No blocked ports. I have to re-install and re-start the computer many times including running the uninstall script (versus moving the app to the trash). 
    Any pointers are appreciated.
