At the Minion troubleshooting guide thread there is soething about java switch to/from IPv6 ntwork protocoll.
If Minion is not able to connect to the internet try to open a Windows CMD prompt (press WINDOWS KEY, type cmd, right click found entry "Command prompt" and choose "Run as administartor") and enter this command:
Code:
setx _JAVA_OPTIONS -Djava.net.preferIPv4Stack=true
Sometimes a pc reboot is needed after this change was done, or at least a disable + enable of your network adapter.
Did you try that as well? Maybe the network traffic is just not initialized due to a protocoll problem.
Else I'd be lost as well and cannot help any further, very sorry.
