Hi,
same issue here: under Windows 10, the "login" command (giving username/password) only brings to the login screen, where the fields are left empty and no login occours... 🤒

Hi. I have the same issu as 153ht. I need , from a server 172.16.100.2, to wake up machines that are in others vlan 172.16.10.x, 172.16.11.x....
What should I do ? Is there commands to implement the broadcast address in veyon ?
thanks

The version 4.8.0.4 have resolved the problem of black screen. But I realised that we can not login a session for multiple computers. Is there a bug for this function too?

HI. Can you be more precise with your solution. In my case the WOL is working fine, the BIOS is well configured and I can start the machine with koxoComputers for Example. But whith VEYON it doesn't work. Where did you put your configuration in veyonConfigurator? thanks

I tried this again with the new version 4.8.0.4 and ran into the same problem, so I had a deeper look and finally found the problem: starting with version 4.7.5.0, the Veyon setup program is incompatible with mandatory ASLR.

Mandatory ASLR is an additional exploit protection you can enable in the Windows Security app under "App & browser control", or through group policy like I did.

To work around the problem, I included an exception for tthe Veyon installer in the MitigationPolicy.xml I am distributing through group policy. It looks like this:

<?xml version="1.0" encoding="UTF-8"?> <MitigationPolicy> <SystemConfig> <ASLR ForceRelocateImages="true" RequireInfo="false" /> </SystemConfig> <AppConfig Executable="veyon-4.8.0.4-win64-setup.exe"> <ASLR ForceRelocateImages="false" /> </AppConfig> </MitigationPolicy>

Bump. Help please

On Windows 11:
%APPDATA%\Veyon\Config\VeyonMaster.json

The folder on Windows is:
%APPDATA%\Veyon\Config
the file:
%APPDATA%\Veyon\Config\VeyonMaster.json

I have one room with 16 student-PC which I updated to Win11. Bulk-Login works on three student-pcs (always the same three). All Clients are installed exactly the same.

I have built myself the following solution:
(Rollout via GPO)

New task in task scheduling Trigger on login + repeat every hour Start program

Script: C:\Program Files\Veyon\veyon-cli.exe
Arguments: config import "\network-share\veyon-config.json".

Works wonderfully 🙂
