Issue Adding Second SSL

Hi, I successfully installed a free ssl certificate on the very first domain I set up inside cPanel. It seemed to go off without a hitch. And indeed it's trucking along perfectly with the green "secure" in the browser window etc.. However, I have been unable to repeat the process for subsequent domains. Before I post some log file information I'll give you some basic system information: /etc/redhat-release:CentOS Linux release 7.4.1708 (Core) /usr/local/cpanel/version:11.68.0.28 /var/cpanel/envtype:kvm CPANEL=release So, I have been pulling my hair out on this as I've done this sort of thing before countless times with the Vesta control panel. I have tried both the let's encrypt auto ssl and the cpanel powered by comodo version as well. I have spent over a day with this on my own and for the life of me I can't straighten it out on my own. I have not opened a support ticket or sought support elsewhere. Here is my log output information: // for the Let"s Encrypt Log for the AutoSSL run for "pcclinictx": Sunday, February 4, 2018 4:36:42 PM GMT+0800 (Let"s Encrypt") 4:36:42 PM This system has AutoSSL set to use "Let"s Encrypt"". 4:36:42 PM Checking websites for "pcclinictx" " 4:36:42 PM The website "example.com", owned by "pcclinictx", has a faulty SSL certificate (OPENSSL_VERIFY:0:18:DEPTH_ZERO_SELF_SIGNED_CERT NOT_ALL_DOMAINS).
