Hostname is the most important thing in Linux server, it is associate with mails, rdns and many other services. A valid hostname can offer you issue free operation. Enough i explained lets get started with the guide.

Step 1 :

Ensure you’ve valid subdomain created from your main domain i.e. if your main domain is then the hostname/subdomain should be like this : or or

Step 2 :

Then whatever you choose the hostname ensure you’ve valid “A” record DNS added eg :

Step 3 :

Go to CWP.Admin by using root user and navigate to :

CWP.admin >> Server Settings >> Change Hostname

Now You’ll see change hostname module where you can set hostname double check to add A record DNS from step 2 Enter the hostname in “New Hostname:” field and hit “Change Hostname” button thats it it will automatically install SSL for hostname you can access cwp in https too :

thats it all done start using CWP.

It will install LE certs, if you’ve self sign cert after changing hostname then you’ve this reasons:
A record dns for hostname is not there
LE CA-server blocks your hostname because of rate limit.

HI Sandeep,

Need your support.

I am facing an issue that is I am using CWP as a Control Panel. Hostname as domain I have properly configured with SSL but if the accessing through IP (instead of domain), the entire site with port can be accessible without SSL.

I want all the users to restrict to use IP address. I want to redirect my server IP to particular domain. Can you please tell me the path where I can rewrite to my domain if I am using CWP.
