HttpAdapterException: ERROR_IN_SOCKET_CREATION, excess private key

[sahana_ps]

Hello,

We recently renewed our client certificate in SAP PO which is used in receiver HTTP adapter after which we started getting below error:

MP: exception caught with cause com.sap.aii.adapter.http.api.HttpAdapterException: ERROR_IN_SOCKET_CREATION, excess private key

The flow is SAP Backend -> SAP PO-> Third party application.

If I use same client certificate in SOAP or REST receiver adapter it works .This error is coming only in HTTP receiver adapter. Similarly, if I use some other client certificate which is working in SOAP or REST in this HTTP receiver adapter I get this error again.

Can someone please guide here? What may be the problem and how to resolve it ?

Thanks,
Sahana
