Syncthing on CentOS 7 keeps Failing

Hey I followed the steps for setting up syncthing on CentOS 7 from this website. But when I start the service i get the following message:

And it keeps restarting over and over again. I tried the guide on CentOS 8 but there’s no issue so far. Is there something I should change or reconfigure? Thanks

Got it fixed via the documentation. There was something wrong with the systemd file after all.
