Add -l to your systemctl status vncserver@:2.service so that we can see the full content of the messages.

Please don't post images. That's so small as to be unreadable. Text works so much better.

PIDFile=/home/root/.vnc/%H%i.pid

That doesn't look right. If the path even exists then I bet selinux won't like it. PID files should be under /run not under /home
