Right now, that's not what I get. See below.

I'm not getting:
1 s:/C=US/O=Let's Encrypt/CN=R3
i:/O=Digital Signature Trust Co./CN=DST Root CA X3
$ openssl s_client -connect bennettconstruction.us:443 -servername bennettconstruction.us
gives me:
depth=0 CN = bennettconstruction.us
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 CN = bennettconstruction.us
verify error:num=20:unable to get local issuer certificate
verify return:1

I lowered the encryption to the most permissive to rule out any problems
with other software being out of date. Didn't help. Might have done that
after sending this thread.

So, as far as I can see, there is:
/etc/ssl/cert.pem
/etc/acme/letsencrypt-privkey.pem (I didn't notice this file until
looking at acme-client.conf
Are there any other files I didn't notice?

OK, didn't know that. Thanks.
I'll play around with this new info and see what I get. I'll post
whatever works or fails either way.
I'll also do some more reading, but not on the Apache site. I hate to
criticize, but the documentation there just isn't maintained and is very
dated.
Appreciate the help.
