System Service (not found)

I’m spinning up a new game server on Ubuntu Server 18.04 LTS and using Systemd to start the services. After creating the service files and a daemon-reload I was able to start the services with no errors but I learned that i had forgot a command in the file. After stopping the services i edited the service files and did another daemon-reload and restarted the services. So the problem I’m having is that when starting the services they return the error of “service not found” even after a full system reboot. Any help is appreciated.

Thank You

Here is the cofig file (all five files are the same other then map names and save Dirs)

Description=ARK Survial Evolved Ragnarok

Attempted to remove disk file system, and we can't allow that.

If you put the originals back (or remove the command that you forgot) does it start working again? Sounds like you entered something it doesn’t like. On further inspection you appear to be calling /bin/killall and the output from systemd-analyze suggests that it doesn’t exist (or I guess the current user did not have permission to X it?)

It also (and I’m not totally familiar with this but) looks like you are typing
sudo service ark_ragnarok.service start
when maybe the command you want is
sudo service ark_ragnarok start
