Thanks, sorry but I've not tested with freeBSD.
I've slightly modified your patch, can you to substitute the address_info() property with the following code in the server.py?

@property
def address_info(self):
        if not self._address_info or (datetime.now() - self._address_info_resolved_time).seconds > ADDRESS_INFO_REFRESH_TIME:
            # converts addresses tuple to list and adds a 6th parameter for availability (None = not checked, True = available, False=not available) and a 7th parameter for the checking time
            addresses = None
            try:
                addresses = socket.getaddrinfo(self.host, self.port, socket.AF_UNSPEC, socket.SOCK_STREAM, socket.IPPROTO_TCP, socket.AI_ADDRCONFIG | socket.AI_V4MAPPED)
            except socket.gaierror:
                pass

            if not addresses:  # if addresses not found or raised an exception (for example for bad flags) tries again without flags
                try:
                    addresses = socket.getaddrinfo(self.host, self.port, socket.AF_UNSPEC, socket.SOCK_STREAM, socket.IPPROTO_TCP)
                except socket.gaierror:
                    pass

            if addresses:
                self._address_info = [list(address) + [None, None] for address in addresses]
                self._address_info_resolved_time = datetime.now()
            else:
                self._address_info = []
                self._address_info_resolved_time = None
        return self._address_info

Let me know if this works. It tries with the flags and if get a gaierror or the addresses list is empty (because of the AI_ADDRCONFIG) it tries without any flags.

Thanks,
Giovanni

Giovanni,

I ran into the same issue on FreeBSD. Your patch works for me.

Thanks,
Erik

Hello and sorry for late reply.

I've just tested your new implementation of the address_info property, and it appears to work fine for me.

Thanks,
Andriy.
