"HTTP Receive Failed: SSL Handshake with bkcs-sap-dev.SBIFM.SBIMF.com:44300 failed: SSSLER_PEER_CERT"

While testing the SAP Gateway for the service /PSINDS/DAAK_SRV_SRV
there is
an error which is cropping stating that "Invalid Token detected at
position
16". When I tried to Replay the SAP Gateway client then I am getting an
error "SSL Handshake failed". I have attached the screenshot of the
same.
Kindly check and confirm.
