We have a monitoring service that uses Icinga and currently we get the following error for a domain on our Caddy server.
Date/Time: 2018-03-09 12:43:49 +0100
Additional Info: CRITICAL - Cannot make SSL connection.

I believe the command used to test this is the following after talking to support
openssl s_client -connect domainname:443 -msg -prexit -debug
The only error I see when running this is
verify error:num=20:unable to get local issuer certificate
Is there a bug in Caddy causing this or is it something I can do on my end to fix this?
