AS400 RPGLE unable to consume REST API with SSL - rest

Question

I have successfully used IBM AxiscTransport API in AS400 (i 7.2) to consume REST API with HTTP. However, when there is SSL, my program fails with the following error.
TransportFlush() call failed: 55:AxisTransportException: Cannot open a channel
to the remote end. Failed to open connection to server, the operation gsk_secure_soc_init() failed. GSKit Error is 410 - Peer not recognized or badly formatted message received.
My sample source code:
uri = 'https://jsonplaceholder.typicode.com/posts/1';
propBuf = 'GET' + X'00';
axiscTransportSetProperty(tHandle: AXISC_PROPERTY_HTTP_METHOD: %addr(propBuf));
propBuf = 'xx.xx.xx.xx' + X'00';
propInt = 80;
rc = axiscTransportSetProperty(tHandle:AXISC_PROPERTY_HTTP_PROXY:
%addr(propBuf):
%addr(propInt));
propBuf3 = 'true' + X'00';
rc = axiscTransportSetProperty(tHandle: AXISC_PROPERTY_HTTP_PROXYSSL:
%addr(propBuf3));
NONE = 'NONE' + X'00';
propBuf = '/QIBM/USERDATA/ICSS/CERT/SERVER/DEFAULT.KDB' + X'00';
propBuf3 = 'true' + X'00';
rc = axiscTransportSetProperty(tHandle: AXISC_PROPERTY_HTTP_SSL:
%addr(propBuf):
%addr(NULLSTR):%addr(NULLSTR):
%addr(NONE):%addr(NONE):
%addr(NONE):%addr(NONE):
%addr(ENABLED):%addr(propBuf3):*NULL);
propBuf3 = 'true' + X'00';
axiscTransportSetProperty(tHandle: AXISC_PROPERTY_CONVERT_PAYLOAD:
%addr(propBuf3));
I am stuck at this for months, and still unable to resolve it. Any help will be appreciated. Thanks.

I got this working by doing this
pTolerate = 'true' + X'00';
pAppID = 'API_MAN' + X'00';
axiscTransportSetProperty(t
Handle
:AXISC_PROPERTY_HTTP_SSL
:%addr(pKeyRingFile )
:%addr(pKeyRingSorP )
:%addr(pKeyRingLabel)
:%addr(pV2Cipher )
:%addr(pV3Cipher )
:%addr(pTLSCipher )
:%addr(pTLSv11Cipher)
:%addr(pTLSv12Cipher)
:%addr(pTolerate )
:%addr(pAppID ));
The pAppID needs to be setup on the ISeries and the SSL certificate in the store linked to the Application ID.
All other parameters were blanks.
