@tobydox Thanks for your work on this. Your post references 4.4.x and I'm currently using 4.7.4. I've read the articles you linked to and still cannot get Veyon to see into PCs that are being accessed via RDP. My setup: 12 physical PCs for students and one for the teacher. Everyone is remote, even the teacher. Teacher connects and uses Veyon to monitor the students. Students connect via AnyDesk or Remote Desktop. We prefer AnyDesk but sometimes have to fallback on RDP. The teacher cannot monitor the RDP students. In Configurator, I set up the Computers as "192.168.1.100:11101" for example. I've tried 11102, 03, etc. and still have no luck. Is there more? What am I missing?

@fh123 Maybe I'm facing the same issue. As a workaround, instead of restarting the machine, try to unplug and plug the USB mouse back. That seems to work. Have a good day. Carlo.

Solved - application MagicInfo and his uvnc modul made the problem. After killing everything run!

@Prakash-K i'm having the same issue.. Please update once you solve this issue.

@lcrosier Hi, I have this issue starting from Veyon 4.7.5. Hitting the "F5" key on the master PC helps to make all clients visible again. The only temporary solution for me was to roll back the teacher PC to Veyon version 4.7.4, leaving the student PCs with Veyon 4.7.5. I hope this helps. Have a good day. Carlo.

@DCteacher You are very welcome! So it was the public key, good to know. I'm happy you have solved the issue! Have a good day! Carlo

Hello, Thank you for your attention. The options you mentioned are already configured, I researched a little more and found this topic that solved the problem, https://github.com/veyon/veyon/issues/146#issuecomment-342851916 Thanks again.

@darrellsimone The documentation should be read first: https://docs.veyon.io/en/latest/admin/installation.html#installation-on-a-linux-computer The teacher machine needs veyon configurator, the client machines only need veyon master. In principle, you can also access a machine on an external network, although I haven't tried it yet, but you have to enable Veyon on the firewall. If something doesn't work, feel free to ask, I'm happy to help if I can.

@Luigi-Capp I have fixed it with the command "sudo apt-get -f install /home/luigicapp/Scaricati/Temp/veyon_4.7.5.0-ubuntu.jammy_amd64.deb" Luigi Cappellazzo

Are you using the latest version on both teacher and student computers?

A typical mistake is that Veyon add-ons are not installed on student computers. Also make sure to configure the Internet access blocking mechanism client-side. Is the Windows Firewall enabled on student computers? If not, please enable it and don't set any group policy which prevents applications from changing the firewall configuration.
