We are getting an error while connecting to sandbox environment. We get below exception. . Can you please guide me on how to fix this issue ? we are currently using 1.8.2 api for java. This was working till mid of april.  

javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

The javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated doesn't always indicate the specific cause of the issue. You may need to enable the SSL handshake debug by adding the Java VM parameter:

 -Djavax.net.debug=ssl:handshake

 which will give you more useful information.

Are you sure that you are connecting to the sandbox via a TLS 1.2 connection? The sandbox URL  was recently modified to accept only such connections.

we tried to override the TLS seeting to 1.2 from VM arguments and by setting through System.property. We are unable to override the protocol version.
