I have two Macs. An M1 Mac Mini and a 2018 Intel Mac Mini. A few days ago, I was able to connect to both on my phone. Now, I cannot connect to the 2018 Intel Mac Mini. The error I get is:

There was an error connecting to the computer. Error Code: 4.8 (0x8).

I went through the MacOS permissions on Jump Desktop Connect, turned things off then on, restarted the Mac, etc., but I can't connect. Any ideas? I haven't updated the MacOS or anything like that. Thank you!

    Hi,

    Thank you for reaching out to us.
    This issue can sometimes occur if you are using an older version of macOS or an outdated version of Jump Desktop.

    To resolve this, please update Jump Desktop Connect on the remote machine to the latest version. Additionally, ensure that you are connecting to the remote machine using Jump’s Fluid Remote Desktop protocol.

    Thanks

    Thanks for your reply. Yes, I did those things. The 2018 Intel Mac Mini's MacOS is Sequoia 15.1.1 and I uninstalled then reinstalled Jump Desktop Connect with the latest version (7.1.37). Still getting the same error. However, I can connect to my M1 Mac Mini with the same MacOS and version of Jump Desktop Connect just fine. I also already toggled all of the relevant permissions off and on, quit and restarted the app.

    Hi,

    Are you currently using a VPN or have a security app enabled?
    If so, please try temporarily disabling your firewall.
    If you are using a VPN, make sure to allow Jump Desktop hosts in your VPN settings.
    For detailed guidance, please refer to this help article about Jump Desktop hosts:https://support.jumpdesktop.com/hc/en-us/articles/360042490351-Administrators-Guide-For-Jump-Desktop-Connect

    Thanks

    No, none of my devices are using a VPN or firewall. On that article you linked, I don't know how to allow those certificate validation servers through; or is that only if I have a firewall enabled?

    Hi Johnoliver,


    To assist you more efficiently with this issue, we kindly request you to submit a support ticket and share the Jump Desktop Connect logs from the remote machine you are connecting to.
    To retrieve the logs, open Jump Desktop Connect on the remote computer, navigate to Settings, then Diagnostics, and select Diagnostic Logs.
    Save the logs as a ZIP file and attach the entire ZIP file to your support ticket instead of individual files.

    Thanks
