HTTP_AAE with SSL certificate : SECURITY_ERROR, Cannot store non-PrivateKeys

[just_omar_zx]

Dear Experts,

We are trying to connect to new client through https protocol and they are expecting a HTTP(POST) meathod from us to send the data,
However, We weren't able to connect for some reasons, even though we have configured the certificate,

We have followed this link for the channel configuration:

https://blogs.sap.com/2012/09/18/configure-the-httpaae-receiver-communication-channel-with-ssl/

Also, we tried some of the suggestions here,
https://launchpad.support.sap.com/#/notes/1958104

Here are our findings:

- If SSL is checked and Client Certificate is specified in Trusted_CA:
HttpAdapterException: SECURITY_ERROR, Cannot store non-PrivateKeys

- If SSL is checked:
http.api.HttpAdapterException: STATUS_CODE_NOT_OK-Bad Request

-if "srtAuth=true" without checking SSL box:
HttpAdapterException: STATUS_CODE_NOT_OK-notresolvable

Our system is Dual Stack 7.40 and we have confirm from our network team that the connection is going to the partner and getting rejected because of the certificate,

For this scenario:

Sender channel from ECC is SOAP to HTTP_AAE,

Seeking your support if this can work or do you suggest using another adapter that can work instead of HTTP_AAE ?

Regards,
