Can't add containers after root container secured

Here are my steps: Machine 1: Create root container and then fabric using fabric:create Machine 2: Start root container & have it Join Fabric (using fabric:join) Machine 3: Start root container & have it Join Fabric (using fabric:join) Add Machine 2 & 3 to ensemble (using ensemble-add) Deploy "secure" profile as described in https://issues.jboss.org/browse/ENTESB-5097 to enable SSL on the management console For each server, generate key and adding its public key to the truststore. put the keystore and truststore to the same directory /home/daniel/apps/jboss-fuse-6.2.1.redhat-090-manualip/etc/identity.jks. keytool -genkey -v -alias server3 -keypass password -keystore server3.keystore -storepass password -keyalg RSA -keysize 2048 -dname "CN=mydomain.com, OU=organization_unit, O=organisation, ST=State, C=IN" -validity 365 keytool -selfcert -export -v -alias server3 -keypass password -keystore server3.keystore -storepass password -file server3.cer keytool - import -trustcacerts -alias server3 -file server3.cer -keystore truststore.jks Wait ~10 minutes and ensure the containers are now using SSL by using container-info command the logs in these 3 ensemble servers indicated: 2016-06-01 15:27:07,794 | WARN | pool-22-thread-1 | DefaultPullPushPolicy | 140 - io.fabric8.fabric-git - 1.2.0.redhat-621090 | Pull failed because of: org.eclipse.jgit.api.errors.TransportException: https: //10.66.218.175:8443/git/fabric/: cannot open git-upload-pack 2016-06-01 15:27:07,794 | DEBUG | tp1923621252-258 | SslSocketConnector | 86 - org.eclipse.jetty.aggregate.jetty-all-server - 8.1.18.v20150929 | javax.net.ssl.SSLHandshakeException: Received fatal alert: certificate_unknown at sun.security.ssl.Alerts.getSSLException(Alerts.java:192)[:1.8.0_77] at sun.security.ssl.Alerts.getSSLException(Alerts.java:154)[:1.8.0_77] at sun.security.ssl.SSLSocketImpl.recvAlert(SSLSocketImpl.java:2023)[:1.8.0_77] at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:1125)[:1.8.0_77] at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1375)[:1.8.0_77] at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1403)[:1.8.0_77] at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1387)[:1.8.0_77] at org.eclipse.jetty.server.ssl.SslSocketConnector$SslConnectorEndPoint.run(SslSocketConnector.java:665)[86:org.eclipse.jetty.aggregate.jetty-all-server:8.1.18.v20150929] at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:608)[86:org.eclipse.jetty.aggregate.jetty-all-server:8.1.18.v20150929] at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:543)[86:org.eclipse.jetty.aggregate.jetty-all-server:8.1.18.v20150929] at java.lang.
