Epoptes crashes when a client with an invalid server's certificate connects

After launching epoptes I see a preview screen, the user, but only 1 maybe 2 times. Then do not. In the console I have the information:

New connection from 192.168.0.223:36473
Disconnect from 192.168.0.223:36473

Strange, because the computers in the network have addresses 192.168.0.x, and the errors in the console 127.xxx
As if epoptes lose connection with their customers. When you click on the icon of customer information is not displayed if no information
