503 errors after Upgrade to Ghost v4

I saw the post by @filijs this morning here: https://forum.ghost.org/t/possible-solution-of-error-502-503-when-upgrading-to-ghost-v4/20943

I tried every command in there and it still did not fix my issue.
I went on https://blog.jonsdocs.org.uk/2019/06/30/problems-with-systemd-ghost-and-node/ to see if it could help, but when I do ghost start and sudo systemctl status ghost_ghost-instance I have a beautiful green light and no errors.

Here is the output:

ghostU@ghostM:/var/www/ghost$ sudo systemctl status ghost_ghost-instance

Here is my /etc/systemd/system/ghost_ghost-instance.service file:
