Error while consuming REST service over HTTPs - rest

Question

I have a simple REST HTTPS POST, the uri of it is like that: https://paymentservicestest.informa.com/mcas_services.asp?
which works perfectly to run in a browser, Postman, etc. With Mule 3.8 HTTP I select the uri from the RAML generataed specification, set uri-param and still I am getting an exception and Code below.
ERROR 2016-10-11 16:16:52,944 [[tstconnection].HTTP_Listener_Configuration.worker.01] org.mule.module.http.internal.request.DefaultHttpRequester: Remote host closed connection. Possible SSL/TLS handshake issue. Check protocols, cipher suites and certificate set up. Use -Djavax.net.debug=handshake for further debugging.

Answer 1

It looks like you have a typo in your URI
I can see from your post that the actual URI should be:
https://paymentservices.informa.com/
whilst in your config you are calling the following URI:
https://paymentservice.informa.com/
make sure you include the 's' in "services", this should at least make a successful request to the correct server.
Change your HTTP_Request_Configuration to:
<?xml version="1.0" encoding="UTF-8"?>
<mule
...
<http:request-config name="HTTP_Request_Configuration" protocol="HTTPS" host="paymentservices.informa.com" port="443" connectionIdleTimeout="300000" responseTimeout="300000" doc:name="HTTP Request Configuration" />
...
</mule>
