There is a bug where you get returned cat: /home/cyberpanel/8553: No such file or directory. Happened on two different (one old and one fresh) VPS servers with CyberPanel on top.
I reported issue in detail here: https://community.cyberpanel.net/t/bug-cat-home-cyberpanel-no-such-file-or-directory/37933?u=richardevcom
I submitted it in your GitHub repo issues as well.
