Cannot obtain ssl for server.mydomain.com

[Namaste]

I have a c8 install and cannot get ssl on host.  So I decided to install a new C7 droplet.   And I still cannot get a ssl for server.

At the moment I am still using linode host name  https://li178-48.members.linode.com:2031/login/index.php

This driving me crazy.  I have been trying to troubleshoot this for months.

I did a clean install, centos 7.   I still cannot get a valid cert for server.  All I get is a self signed cert.  What is wrong?

Try to check the log /root/.acme.sh/acme.sh.log once you trying to issue LE cert
