May you facing an ipv6 incompatibility problem:
"I discovered a solution from a response to my post on the main Maven user forum. They suggested that I had run into an IPv4 vs IPv6 incompatibility problem and recommended either disabling IPv6 on my network adapter or using the -Djava.net.preferIPv4Stack=true VM arg. I tried disabling the network adapter and that had no effect but the VM arg (via _JAVA_OPTIONS env variable) solved the problem."

Just disabling the protocol binding may not help, because your DNS cache has an IPV6 address already.
It's just an idea. I don't use minion.
