Curl error 'Couldn't connect to host'

Content

Hi all,

I am writing a custom script in cPHP which makes POST requests to webservice API using Curl.

I have tested the API using external tools (postman) from my computer and it worked fine but when I try to implement it from custom script using curl, I am getting an error saying 'Couldn't connect to host'. 

is there any restriction/configuration requirements in RightNow which is preventing me to connect to API?
