Pritunl : Error getting LetsEncrypt certificate

Hi,

Ran these commands

curl -6 ifconfig.co - nothing
curl -4 ifconfig.co - Spat out my public ip.

httpd -S - Returned :
Command 'httpd' not found, did you mean:

command 'http' from snap http (2.3.0)
command 'xttpd' from deb xtide (2.13.2-1build2)
command 'http' from deb httpie (1.0.3-2)

See 'snap info ' for additional versions.

The installation guides i use is here : https://docs.pritunl.com/docs/installation and followed the start of the config page.

I didn't see what web service was installled when i ran through the steps. (I assumed it was apache)

I may be able to spin up a VM and do a test run and see what gets installed if it is needed.
