Nagios Core on Ubuntu 18.04

I am having multiple issues getting Nagios Core to work properly. First and foremost when I was actually able to start it, in the web interface it was telling me "Not Connected" however now I can't even run sudo systemctl start nagios.service without receiving this message:

Job for nagios.service failed because the control process exited with error code. See "systemctl status nagios.service" and "journalctl -xe" for details.

Nagios Core v.4.4.5 Ubuntu: 18.04

I will post the systemctl and journalctl in a comment, I'm getting a "this looks like spam."

This is far above my skill level as I know very basic commands, as much as I'd like to learn everything there is on Linux, unfortunately I haven't had the time :/

Thanks for anyone's help in advance!
