SM59 - Type G connection failure - ICM_HTTP_CONNECTION_FAILED

Question

I need to setup an SSL communication to a third party.
The HTTPS port 8443 has been configured for this
If I use function module HTTP_POST with a URL
e.g  https://test.support.example.com/post/CreditCardAPIReceiver
I can correctly connect and get a response back.
If I try and create an SM59 destination.
Connection type G
Host = test.support.example.com
path = post/CreditCardAPIReceiver
service = 8443
I have tried all combinations for security options:
SSL Inactive/active  and with standard client and annonymous
When testing the connection I get   ICM_HTTP_CONNECTION_FAILED.
has anybody got any ideas what i'm doing wrong.

Answer 1

Thanks for you response Raja.
The third party we are connecting to has  a TEST environment  which doesn't require a digital certificate authentication. This is initially what I'm trying to connect through via SM59. So I'm still posting to a HTTPS:// but there is no digital certificate.
I can post and get a response from the same URL when using HTTP_POST and specifiying URL.
However if I try and create the same information in SM59 and either test the connection or use cl_http_client=>create_by_destination to post a request I cannot connect to there server.
I've also tried connecting to there Production environment which does require a digital certifcate.  I've loaded the digital certificates into the Anonymous client but still cannot connect when testing the connection in SM59.
