Everything works for me with latest server(from development branch):
[25-Jun-2016 17:37:04.267] [DEBUG] Beacon host 195.13.231.157 added
[25-Jun-2016 17:37:04.267] [DEBUG] Beacon host 8.8.8.8 added
[25-Jun-2016 17:37:04.267] [DEBUG] Beacon poller thread started
Host configuration: "google.com,8.8.8.8"
What version do you use? May it happen that there were some DNS problems?
