Minion and IPV6 or "cannot connect to the internet"
 

After getting the "cannot connect" error most of the times i tried to open the Program and temporary disabling firewalls without any success i found this error in the log files:

Mär 15, 2015 11:57:51 AM org.apache.http.impl.execchain.RetryExec execute
INFORMATION: I/O exception (java.net.SocketException) caught when processing request: Address family not supported by protocol family: connect

It seams that Minion cannot connect over IPV6 and my pc is unsing this as default.
Setting the option to use ipv4 solved the problem.

Maybe you can add a fallback to ipv4 or the system-property in general to the source of minion.
