SAP HANA Trial:
ES5 Connection is failing with the message "Peer not Authenticated".
Behaviour is the same from WebIDE or Check connection @ Destinations.
When you directly access "https://sapes5.sapdevcenter.com/sap/bc/gui/sap/its/webgui?sap-client=002&sap-language=EN". Browser says it is not secure and when you verify the certificate it says expired, validity was 21 Feb 2018 to 21 April 2019 @"Go Daddy Secure Certificate Authority - G2".
So, I believe this is the reason for failure. Any idea whom to tag here.
