vnc - 18.04 x11vnc failed to start and password problems

18.04 Ubuntu and 9.13 x11vnc installed. I'm trying to set up my PC so I can VNC into my current session and have x11vnc run at startup. If I don't set a password I can vnc into my PC's current session fine on port 5900. When I set a password I cannot connect in. I can however connect into a new session on port 5901 which is not what I want.

On top of that, when I try create a service file to run at startup, I get a failed to start x11vnc message.

I'm using this blog: http://c-nergy.be/blog/?p=12220 as my guide.

Below is the output I get when I try to start the service:

user@ubuntu-pc:/lib/systemd/system$ sudo systemctl enable x11vnc.service
user@ubuntu-pc:/lib/systemd/system$ sudo systemctl daemon-reload
user@ubuntu-pc:/lib/systemd/system$ sudo systemctl start x11vnc.service
user@ubuntu-pc:/lib/systemd/system$ sudo systemctl status x11vnc.service

Any help is appreciated.

Edit 1 When I attempt to VNC in I get "connection attempt refused" then I run x11vnc and VNC in at port 5900 with no password, then I can see my current screen. After running x11vnc -storepasswd /home/ then x11vnc -rfbauth /home/hudsona/.vnc/passwd I can VNC into my current session with a password.

Edit 2 After creating that .desktop file from the question I linked in Edit 1, I can reboot, log in then VNC from another machine on port 5900 and get in. Without logging in I can VNC in from another machine on port 5901 but on my VNC viewer all I get is a grey checkered screen with an "X" mouse cursor.
