Hai, Thanks for replying. I have already tried connecting to the "openwire" connector from an mqtt client without ssl and it worked. Also tried connecting to the ssl connector without the client certificates and the case remains the same: 2015-04-01 12:41:11,941 | WARN | Transport Connection to: tcp://10.30.9.254:59032 failed: java.io.IOException: Unknown data type: 77 | org.apache.activemq.broker.TransportConnection.Transport | ActiveMQ Transport: ssl:///10.30.9.254:59032 2015-04-01 12:41:16,517 | WARN | Transport Connection to: tcp://10.30.9.254:59033 failed: javax.net.ssl.SSLHandshakeException: Invalid TLS padding data | org.apache.activemq.broker.TransportConnection.Transport | ActiveMQ Transport: ssl:///10.30.9.254:59033 2015-04-01 12:41:17,591 | WARN | Transport Connection to: tcp://10.30.9.254:59034 failed: javax.net.ssl.SSLHandshakeException: Invalid Padding length: 218 | org.apache.activemq.broker.TransportConnection.Transport | ActiveMQ Transport: ssl:///10.30.9.254:59034 -- View this message in context: http://activemq.2283324.n4.nabble.com/Invalid-TLS-Padding-data-Error-while-trying-to-connect-ActiveMQ-via-SSL-tp4694099p4694184.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
