Well, I am not sure what documents you have been reading, but your config looks a bit of a mess.
First, what versions of letsencrypt and dehydrated are you using please?
rpm -qa |grep letsencrypt
rpm -qa |grep dehydrated
Your config:
letsencrypt=service
Do you understand what this does? it enables certificates for ALL hosts and domains. Are they all resolvable?
configure=all
This is set but does not appear in your config file?
email=admin@buzz.kerplouz.com
What is this for? You need to set required entries in the hosts and domains DBs, not here. Please remove it.
host=buzz.kerplouz.com
Why is this set? It is fixed in the config file, and should be removed from here.
path=/home/e-smith/files/ibays/Primary/html/.well-known/acme-challenge
At least one good thing
status=test
Why is this set? It will not work and can be removed.
user=root
cat /etc/dehydrated/domains.txt
As per the config item above, does every one of those host and domains resolve correctly ? If not you will get a failure.
Please go back and read the documentation.
