Are you binding to a specific port? If so try changing the port does it
work. You can also specify the port to be 0 in which case the stack will
choose a free port for you.

If the above step fails or you're already binding to 0, try binding to
address 0 (techinically INADDR_ANY), again the stack will pick an
appropriate interface for you. After doing binding to ip address INADDR_ANY,
and port 0, assuming you succeed you can get the address that it bound to
and make sure that it was the same one you were trying.

Another common mistake is that you may be using the address with the bytes
in the wrong order try binding with net_long(ipaddr).
