Service Start/Stop Buttons Grayed Out(Linuxmint)

[onurtamer]

What should I do to start the service? Installed the app through package manager and via .deb but everytime I having the same problem. Tried many linux distros, followed many step-by-step solutions but couldnt start master or client.

Are you using one of the Veyon 4.1 pre-releases? I'm asking because in Veyon 4.0 there's no proper system service support on Linux yet.

Solved that problem by installing 4.1.4 but this time I have another problem with the service. The "veyon-service" seems running properly on every pc including the master pc but clients' previews goes red randomly on master and not responding until I use "sudo service veyon-service restart" command via SSH. Sometimes master pc needs that command or need stop and start the service on Veyon-Configurator to use Veyon Master.
PS: Tray icons dissappear when this problem occurs but service still seems fine.

The service "only" launches server instances inside user sessions so if the tray icon disappears certainly the server crashed. This is quite hard to debug. Which distro/version and desktop environment are you using? Can you try to set the log level to debug on clients and examine the server and service log files?

Using Linuxmint 19 Tara and XFCE desktop. I don't know what to examine but I uploaded the log files in my google drive, here is the link to it.
