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. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: https://newcompanies.glazingo.com
I ran this command:
It produced this output:
My web server is (include version): webmin
The operating system my web server runs on is (include version): Ubuntu 20.04.1
My hosting provider, if applicable, is: AWS
I can login to a root shell on my machine (yes or no, or I don't know): Yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): Webmin
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you're using Certbot): certbot 0.40.0
[https://domain.com]has a Free LetsEncrypt SSL using Virtualmin but when someone register on that website, it automatically create a sub-domain [https://ab.domain.com] and created sub-domain is shown as Non-Secure tag in URL with a invalid certificate.
Is there anyway to implement a Free SSL on sub-domain?
I am still figuring out.
