Thank you for letting us know there is possibly an issue.

Please double check the systemctl command was exicuted as root not a regular user.  

If that does not help can you please post your "/etc/systemd/system/vncserver@.service" file. 

Thanks !

Hi,  Well this seems to be all fine.  

Can you please let me know the version/distro you are using?

Are you using one of the Linux Foundation images?

Please let me know the version of vncserver and systemd you are using.

Thanks

Hi,  The CentOs image was downloaded from CentOs web.

Hi, I retested it on a clean installation and duplicated your issue. It is a typo in the example file. The PID specification has the wrong user name in it.

Incorrect:

PIDFile=/home/lee/.vnc/%H:%i.pid  

Correct:

PIDFile=/home/student/.vnc/%H:%i.pid

Thank you for pointing this out, it will be corrected in the next version.
