The modules for imitation rdp, redis, git and vnc protocols don't use "device.listen_addr" parameter from config file. So there is no problem if you have only IPv4 network interfaces on your host where Opencanary is running as it runs on all ipv4 addresses by default. But if you have only IPv6 network this modules cannot be used.
I simply added self.listen_addr just as it is in other modules
