CWP: Auto_SSL is not working from both Admin/User Panel [Fixed]

Auto_SSL location For Admin Panel: WeServer Settings >> SSL Certificates
Auto_SSL location For User Panel: Domain >> AutoSSL

Both are not working when i try install ssl certificate for my parent & sub-domain.

Error Type:
"ErrorErrorInvalid Domainfile_get_contents(/usr/local/cwp/.conf/vhosts-ssl.json): failed to open stream: No such file or directory"
DNS Issues , .htacess issue

Solutions: Goto Server Settings >> Change Hostname >> Click on Change Hostname

Then Install Auto SSL from Admin Panel , Restart & Reload WebServer . If success then
Install another Auto SSL for another sub-domain , If success then Okay . Now login to your user panel and Install AutoSSL .
