Hello @varaande 

when you encounter a "java.net.UnknownHostException: www.abc.com," it signifies that Java, and likely the operating system beneath it, is incapable of converting the "www.abc.com" hostname into an IP address. This usually indicates there is an issue with DNS resolution. May be machine isn't intended to resolve this specific hostname.
