POSTMan gives valid resposne for the API, but SoapUI gives respose HTTP/1.1 405 Method Not Allowed

Hi All,

My requests to the server gives the below response from the soap UI 

HTTP/1.1 405 Method Not Allowed
Allow: OPTIONS
Server: akka-http/2.3.12
Date: Wed, 11 Nov 2015 02:38:23 GMT
Content-Type: text/plain; charset=UTF-8
Content-Length: 51

HTTP method not allowed, supported methods: OPTIONS

while post man client gives the valid response, and gives the expected results. can any one suggest what could be the issue
