!!!Cannot assign requested address
You are attempting to bind(2) to a local address that isn't local. For example if the IP addresses of a machine are 127.0.0.1 and 188.8.131.52, and you're trying to bind to 184.108.40.206 you are going to get this error. Check to make sure the address you are trying to bind to exists on the machine you are trying to bind it from.
