We're happy to announce Veyon 4.10.4, the fourth maintenance release of Veyon 4.10.x. This release primarily fixes a performance regression in Veyon Master resulting from the thumbnail layouting improvement in 4.10.3. Additionally it's now possible to specify a prefix or suffix by which to extend the identity of guest users automatically such that for example valid exam users can easily be recognized. All downloads for this release are available in the download area. A complete list of changes in detail can be found below: Core Improve robustness by using std::vsnprintf() instead of sprintf()/snprintf() Add various size checks when receiving usernames, signatures and tokens Master Fixed performance regression introduced with improved thumbnail layouting in 4.10.3 Added support for extending guest user identities with prefix or suffix Plugins Demo: don't lock the master computer when sharing a user's screen fullscreen (#1126) Linux Added Nix flake and NixOS module Windows 3rdparty: UltraVNC: update to 1.8.2.3

Buenas a todos Tengo veyon actualizado a versión 4.11 tanto en master como en clientes. La utenticación la hago mediante certificados. Y no funciona la opción Demo (proyectar pantalla), pues se queda con el simbolo del círculito dando vueltas sin proyectar en los clientes lo que le mandas. [image: 1789118472795-captura-de-pantalla-2026-09-10-123619.png] Si ponemos autenticación por inicio de sesión si que funciona. Si ponemos versión anterior 4.8 con autenticación de certificados si que funciona. ¿Le sucede esto a alguno más? ¿Alguien sabe como resolverlo? Gracias

Just started today our computer teacher and I were experiencing an issue with the open website button. Out of the 27 computers in that lab, 9 of them would not open a browser when doing open website button. All of these computers were imaged over the summer using a base image so I know there is no variations between the 27 computers. I tried the following: updating Veyon uninstall/reinstall of Veyon Clearing the Veyon configuration Deleting the computer leases at a DHCP and rebooting the PC's Ran any Chrome updates Uninstall and reinstalled Chrome Deleted the windows user profile from those 9 computers Made sure Google Chrome was set as the default browser sfc /scannow I also tried the start application button and pasting in "C:\Program Files\Google\Chrome\Application\chrome.exe" and it would not open Chrome on those 9, but did open Chrome when trying it through the rest of the computers. If I open up the run command on the computers directly and paste that same path in it opens up Google Chrome. So I know it's not an issue with where the install location is on those nine computers. Which couldn't be an issue anyway because all 27 computers are based on the same image. Anyone have any suggestions?
