Systemd Failure On Detailed Install

Followed the steps:
https://simplex.chat/docs/server.html
Started a new install of xmq and came across an issue at step 5. Optional — If you're using distribution with systemd, create /etc/systemd/system/smp-server.service file with the following content:

When running the systemd service it shows an error

dmesg: Output: shows nothing

I tried moving forward to the caddy section where I encountered a second issue
step 6 of the Caddy install
Make the script executable and execute it:
Error:
:/usr/local/bin# chmod +x /usr/local/bin/simplex-servers-certs && /usr/local/bin/simplex-servers-certs cp: cannot stat '/var/lib/caddy/.local/share/caddy/certificates/acme-v02.api.letsencrypt.org-directory/smp.MYDOMAIN.link/smp.MYDOMAIN.link.crt': No such file or directory

If anyone could give me some direction on where I am going wrong with the detailed install steps, I would be grateful.

Start with the server installation steps at https://simplex.chat/docs/server.html, especially the systemd service definition and Caddy step 6. Trace how simplex-servers-certs obtains the certificate and compare it with the paths and service errors reported here; done means the documented sequence works for a fresh install and the service reaches an active state.
