VNC service failed to start for a certain user

[yildizabdullah]

I noticed that one of the users were unable to access the machine via VNC after starting the machine.

When I check the service status, I have the following message:

Code: Select all

systemctl status vncserver@\:38.service
● vncserver@:38.service - Remote desktop service (VNC)
   Loaded: loaded (/etc/systemd/system/vncserver@:38.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Sun 2024-01-28 20:20:52 +03; 15h ago
  Process: 1849 ExecStart=/usr/bin/vncserver_wrapper user1 %i (code=exited, status=2)
  Process: 1759 ExecStartPre=/bin/sh -c /usr/bin/vncserver -kill %i > /dev/null 2>&1 || : (code=exited, status=0/SUCCESS)
 Main PID: 1849 (code=exited, status=2)

How can I check or understand what caused this issue? This also happened last week for another user.

Do you see anything with:

Code: Select all

journalctl -u vncserver@\:38.service

Please ignore the last few lines as I started the session manually with

Code: Select all

systemctl start vncserver@\:38.service

Read /home/user1/.vnc/centos7-server:38.log

I think it is overwritten when I restart the service as everything looks normal to me.

I attached the log file for your information.
