Ssl generating on server where dns pointing to single server


Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:
with subdomain pointing to it via dns

I ran this command:

It produced this output:

My web server is (include version):
the webserver is on apache ngix
The operating system my web server runs on is (include version):
debian strech
My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know):
can login with root
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):



Can you specify your question?

Thank you


Hi Sir,

few other add from different domain register account pointing to it such as:

how should i do the certificate . as i in the development stage for the server.


basically sir , it is a sip server.


Hi, in this case I suggest use DNS validation.

Since I’m not sure what is the use of certificates.


Hi steven,
the ssl use for sip server tls services and also the web server control pabel for the services .


You can use http validation with certbot --standalone (not having any nginx apache server).

You can also use DNS validation if you can add all record (and have api access if you want to automate the issurance, renew)

Thank you
