Urgent Technical Support Required – Veyon Stopped Working on November 4th

[IZABELY]

Hello Veyon Support Team,

I am requesting technical assistance regarding an issue with Veyon in our computer laboratory.

We have 30 computers running Windows 11 (1 teacher's computer and 29 student computers), all connected through a wired local network.

Veyon was properly installed and configured, and everything was working normally in the morning of November 4th. However, at approximately 1:00 PM (13:00), the software suddenly stopped working correctly.

The computers are still listed in Veyon Master, but several of them no longer display their screens. Some computers show a red lock icon, while others display a gear icon with a red exclamation mark.

We have also tested the network connection using PowerShell with the following command:

Test-NetConnection [STUDENT_COMPUTER_IP] -Port 11100

The result was:

TcpTestSucceeded: False

We would appreciate your assistance in identifying the cause of this issue and providing clear instructions on how to restore the system.

Since the software was correctly configured and was working earlier on the same day, we need to understand what caused this sudden failure and how to prevent it from happening again.

I am attaching a screenshot of the Veyon Master interface to help illustrate the problem.

We urgently need a clear technical explanation and a solution, as this software is essential for monitoring our students' computers during classes.

Thank you for your attention. I look forward to your response.

Best regards,
Computer Laboratory Administrator!
