When trying to send a webservice request from WebSphere Message Broker using a SOAPRequest node to an external webservice provider, the following exception is thrown in the logs:
BIP3165S: An error occurred whilst performing an SSL socket operation. Operation: 'connect'. Error Text:'javax.net.ssl.SSLProtocolException: Server resumed session with wrong protocol version'.
If the remote side of the socket has attempted to resume an SSLSession on a different protocol version, then this could represent a privilege escalation attack. WebSphere Message Broker will (correctly) reject the handshake attempt.
Diagnosing the problem
A JSSE trace and an IP trace should show the protocol change.
Resolving the problem
Ensure network firewalls have provided the necessary access (correct port and protocol access).
