Today at the company I have an internal DNS server on Centos 7.
And it already has a certificate service for a site for example: www.example1.com.br
Today the need arose to have another site for example: www.exemplo2.com.br
But when we use the command certbot --apache -d example2.com.br it doesn't work
In addition to this command, is it necessary to perform another procedure?
It is difficult to say without more details. But, have you setup your public DNS with the correct public IP that routes to that new domain?
Please provide more details especially the exact error message you receive
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.
