It seems as if your standard proxy in your system settings is not supported by Minion:
gg.minion.util.FeedClient:getRoutePlanner(61): System Default Http Proxy.
WARN 2017-03-10 09:01:58,064 [Thread-7] gg.minion.util.FeedClient:run(164): IOException: Address family not supported by protocol family: connect
Check your web browser and there the proxy settings if some malware or other stuff entered a proxy server which you do not know e.g.
and remove it or change it to the correct http proxy.
