ICM_HTTP_SSL_ERROR occurs in connection test (ByDesign)

Hi.

I'm trying to send purchasing data from SAP Business Bydesign to OnPremise SAP ERP.

However, the message, ICM_HTTP_SSL_ERROR occurs when test the connection in the menu of Communication Arrangement.

As SSL client certificate setting, I chose Business Partner Key and imported the downloaded key into the folder Client Anonymous by STRUST.

Does anyone know how to solve the problem ?

Error logs in SMICM are follow,

Thr 4204] SecudeSSL_SessionStart: SSL_accept() failed

Thr 4204]   secude_error 536875074 (0x20001042) = "received a fatal SSLv3 bad certificate alert message from the peer"

Thr 4204] >>            Begin of Secude-SSL Errorstack            >>

Thr 4204] <<            End of Secude-SSL Errorstack

Thanks and Regards,
