Veyon Master doesnt find Clients after new Image

[wittmann-kcs]

Hey,

we have some trouble with our Veyon Client Systems.

After we deployed our new Image on some Computers the Master cant find the Clients.
DNS/IP/Hostnames doesnt change at all.
In fact the Systems are the same with a new Windows Version.
No Windows Firewall, no Security Policies, no IP Change.

The Keys of Veyon are exactly the same and 2 Systems are there (Online, Controllable).
The other 70 Sytsems cant be shown in the Masters Software.

Any Ideas?

Thanks a lot!

PS: We did deveral Tasks of Veyon Troubleshoot but nothing seems to happen.
