Networkerror when trying to fetch resouce/wiki.service failed to run

Disclaimer: I am fairly new to this sort of thing, but I'm the closest we have to an IT guy.

My end goal is to create a wiki that can be accessed through the internet and edited by multiple members of our company.

I have created my localhost postgres server, created a database for my wiki, and set it up with no glaring errors, but when I go to log into the wiki for the first time I get the error in the title, though I stay on the login screen. The server and database are active. I don't even know what this means so I'm lost on how to handle it. I attempted to refresh the page and now it won't connect at all.

When I list the services in Systemctl, the wiki.service is loaded but is failed in the active and running columns. Here is my my config file setup for the service:

[Unit]
Description=Wiki.js
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/node server
Restart=always
Consider creating a dedicated user for Wiki.js here:
User=nobody
Environment=NODE_ENV=production
WorkingDirectory=/home/wiki

[Install]
WantedBy=multi-user.target

One thought I had was that I set the port up as 3000 rather than 80, even though I am not behind a reverse-proxy. I did this because my port 80 was in use and changing it seemed like the easier option at the time.

Another possibility is that my wiki was not installed at /var/ but instead at /home/. Could this be causing the issue, though I made sure to alter that path in the service config file.

The url set for the wiki is hosted on dreamhost and should be available for wiki.js, though I don't necessarily know how to confirm that.

I can't post logs for the service as it does not currently function.q

Any advice would be much appreciated! Thank you.

Host Info (please complete the following information):
OS: Ubuntu 18.04
Wiki.js version: [2.4]
Database engine: [postgres 12.3]
