fix: handle domain names in IP4 configuration variable

Browse Source 
Previously, when the IP4 variable contained a domain name instead of an actual IP address, the SNI validation would fail and force the use of self-signed certificates. This update adds detection and resolution of domain names in the IP4 variable, ensuring proper DNS comparison when checking if the SNI domain points to the server.
