getting error 404 while consuming external REST web service

Hi Experts,

I have written a program where i have to send Json format to external REST web service using HTTP-POST method. But i am getting error http_communication_fail and response code is 404 with reason = 'hostname is unknown'. i am not using any proxy method and RFC.

Is there any thing needs to be done before consuming an external REST web service through link.

sample code and advice is highly appriciated.

    Looks like you have a communication error. The hostname to which you are trying to connect is not known.

    There might be a various reasons why that's the case. The best choice would be to contact one of your system administrators as they are in a position to help you.
