It doesn’t appear to be hosted from public_html then. Maybe ask your hosting provider or site/server admin where the site files are hosted? I see you have CPanel, maybe try accessing the File Manager through CPanel and see what directory the site is hosted from and then use that path on the command line.
I’m sorry but I’m unfamiliar with your setup as it’s self-hosted so I can’t give you an exact path.
Cheers.
