I've had the same for a while now. Version 4.9.0 on the client and up through 4.9.8 on the master. I'll upgrade the client on Monday to see if that resolves the problem (can't RDP into it and can't get to that building today). I should mention that I'm using the UltraVNC that comes with the installer, I'd be happy to use a different VNC if that would fix the issues. Also this is Windows 11 EDU 24h2 on both computers, all MS updates, etc.

Hello We found the solution with the support of PC Sheriff service. Both are using the same VNC for remote access to the Client PCs. PC Sheriff blocks Veyon Service. Solution: user defined installation of PC Sherrif and deselect the installation of UltraVNC Software from PC Sheriff!

Thank you! I will try that over the holiday break and see what happens when the students return. Upon troubleshooting since I made the post, I noticed the "Veyon Server" and "Veyon Worker" are the 2 processes that would continuously restart. The "Veyon service" stayed in the processes list. Based on that is there anything else I should try or do you think this will still do it? Thank You!!

This has been fixed in Veyon 4.9.8

Does upgrading to Veyon 4.9.8 help?

Can you try to add another dependency to the service by running the following command at the command line (requires admin privileges): sc config VeyonService depend= tcpip/rpcss/lanmanworkstation/lsm/dnscache This adds the lanmanworkstation and dnscache services as dependencies.

Please use /NoMaster

I have noticed the same thing. Also, when you copy and past the "@" symbol everything works as well. The program adds an extra, unseen character before the "@". [image: 1764938434524-bc1994a6-1a40-41a2-8dda-8d9a496b197e-image.png]

Is it on the same subnet? Is Wake-on-LAN enabled on the NIC and/or BIOS?

I believe that's the "Authentication" icon. How are you authenticating to the machines? Perhaps a missing authentication key on the client?
