In this tutorial We'll install Lets Encrypt free SSL in  Control web panel, so you can access the admin panel and user panel url in https also for mail server and hostname.

Follow the below steps to get ssl installed.

Step 1 : 

Choose a valid Hostname i.e it should be the subdomain of your main domain example : 

server1.domain.tld
or
alphagnu.domain.tld

** ensure whatever you choose as a hostname url you should have valid A record DNS pointing to the server ip

*** don't choose mail.domain.tld or cpanel.domain.tld or ftp.domain.tld or webmail.domain.tld as this are reserved for cwp admin services.

Step 2 : 

Change the hostname :

Go to CWP-admin >> search >> search for change hostname >> open change hostname module

Step 3 : 

Install Lets encrypt ssl for hostname : 

By entering the hostname click on "change hostname" button that's it the module will install Lets encrypt ssl automatically for hostname, control panel urls and mail server

the hostname module will add ssl to everywhere, now check the admin panel url : https://server1.domain.tld:2031/ and user panel url https://server1.domain.tld:2083 it should be opening with proper ssl certs.

Hi, Thank you very much Dear Sandeep you're always helpful, cwp without unimaginable.   appreciated

But, like many, I have two domains pointing to the same server and IP.
