It turned out to be a hostname reverse lookup issue. If NetBIOS is still enabled, on each scan Windows performs the reverse lookups randomly either via NetBIOS or DNS, causing different hostnames (NetBIOS: uppercase letters only) to be resolved, making Veyon reconnect to the computers each time the hostname (format) changes.

We got the similar problem, however we are Chinese character user, and we have deployed 12 student computers and start test login by teacher computer. We only got 4 of them can login successfully and other 8 got stucked either in the input method or login box. We are using 4.7.2 teacher master (upgraded from 4.7 after got stucked) and mixed 4.7(8)/4.7.2(4) student, and the result is irregularly got stucked on login. We are trying to find solution in here and anywhere we can go.

Please update to 4.7.2 where screen resolution issues have been improved.

After uninstalling, there may be leftovers in C:\ProgramData\Veyon as well as the user's AppData directory (folder "Veyon" in Local or Roaming). The computer list is stored in the registry, so make sure to remove HKLM\Software\Veyon Solutions.

Hello, I am struggling to get veyon-server to start up automaically at the login screen of Ubuntu 20.04 before any user logs in. I am using the lightdm Display Manager and latest veyon from the ubuntu ppa. We have the ubuntu Desktop Environment for local use and the xfce Desktop Environment for use via RDP. So, once I am inside any user session and run the "veyon-server" command from a terminal, the veyon server starts and establishes a proper connection with the veyon master. Before and after that, I just see the orange screen... I have searched quite a while now and found several related posts to this topic, but this seems to be the newest one. Please tell me if I should post any logs or where I could check proper configuration. Thank you in advance. [image: 1644590495609-veyon-l%C3%A4uft-nicht.png]

Hello All ! I solved my problem in a non-elegant way. I wiped the teacher s disk with an old image. W10 1803. Reinstalled veyon and it worked. Dunno Why. Thanks for your support anyway.
