Unable to access Laptop clients, no problem with desktops.

[Hrossey]

I have installed the Veyon client on various PC's, a mixture of Windows 7 and Windows 10, the clients on the desktop machine can all be accessed without a problem. I tried installing the client on a few laptops with Windows 10, same build and network as the desktops, and I can't access them from the master. They all use a standard default domain GPO so should be set up the same. As a test I reformatted one laptop and did a clean install of Windows 10, this machine can not be seen by the Master either. Any ideas?

Are you using logon authentication or key file authentication? If logon authentication, can you logon into Veyon Master application on a Windows 10 machine?
