If the app won't launch because it is detecting monitoring software - That would be a question for the other apps' developers. Perhaps they have a whitelist or exclusion list you can add to? However, if this is something like a test-monitoring application, they typically do not allow exclusions so as to prevent students from cheating.

I also have this issue with some random computers that refuse to start on their own. I've been unable to fix it. I created a .bat file that I can launch to remotely start the service. Launch it, enter the name/ip of the computer and the service starts: SET /p computer="Enter ComputerName:" sc \%computer% start VeyonService

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?

Hi, I have the same problem with my laptop mouse. The USB mouse stops working. The touchpad works. How do I fix this?

SOLVED: solved the problem. need to disable the virtual network card created by Virtual Box.

welp it was x11vnc that was miss behaving because I am on wayland. Fix it by changing the vnc server.

We are also having this specific issue, particularly with Adobe Premiere Pro, during the Export feature.

Hello, The same problem here. When I log in from “Remote Control,” when I enter my username and password containing @ and press the ALT+GR key, it enters that strange character. In my case, when connected remotely to the machine, nothing strange is displayed with the @, but when I try to enter it in a cmd, for example, I can see how it sends the same symbol with “?”. If you access the machines from Veyon itself with “Log in” instead of connecting to them remotely, it types and sends the @+ALT GR without any problems. I temporarily solve this by using ALT+64 in my case. For any other character, it would be necessary to find the corresponding number for that character in the ASCII table. Even so, as it affects passwords with special characters, it is tedious to work with this bug on a daily basis. If anyone finds a solution, that would be wonderful. Thanks in advance and best regards, [image: 1761051638988-error-veyon.png]
