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.

Also, it seems your thread title does not correspond with the thread contents, as clearly different errors are presented. How does the policy error relate to the hostname you've mentioned in the thread?
And nmap -Pn sbsartis.b2m-it.com seems to confirm this.
$ nmap -Pn sbsartis.b2m-it.com

Apart from the port issue mentioned above, I guess you simply copied the command from user guide and included example.com literally as domain name without any modification, as indicated by the error message in the subject.
The "example.com" domain should not be copied as-is. This should be replaced with your actual domain. in this case, it should be sbsartis.b2m-it.com
