AWS EC2 with S3 PING Wildfly 8.2 session not shared

Question

The two wildfly instances are not in the same session.

I have configured the following parts of the standalone-full-ha.xml :

<subsystem xmlns="urn:jboss:domain:modcluster:1.2">
           <mod-cluster-config advertise-socket="modcluster" proxy-    list="10.0.0.146:6666" balancer="mycluster" advertise="false" connector="ajp">
</subsystem>

10.0.0.146 is the apache instance private IP.

<subsystem xmlns="urn:jboss:domain:jgroups:2.0" default-stack="tcp">
            <stack name="tcp">
                <transport type="TCP" socket-binding="jgroups-tcp"/>
                <protocol type="S3_PING">
                <property name="access_key">
                    XXXXXXXXXXXXXXXX
                </property>
                <property name="secret_access_key">
                    XXXXXXXXXXXXXXXXXXXXXXX
                </property>
                <property name="location">
                    wildfly-bucket
                </property>
                <property name="timeout">
                    16000
                </property>
            </protocol>
            <protocol type="MERGE2"/>
            <protocol type="FD_SOCK" socket-binding="jgroups-tcp-fd"/>
            <protocol type="FD"/>
            <protocol type="VERIFY_SUSPECT"/>
            <protocol type="pbcast.NAKACK"/>
            <protocol type="UNICAST3"/>
            <protocol type="pbcast.STABLE"/>
            <protocol type="pbcast.GMS"/>
            <protocol type="MFC"/>
            <protocol type="FRAG2"/>
            <protocol type="RSVP"/>
        </stack>
    </subsystem>

....

<interfaces>
   <interface name="management">
       <inet-address value="${jboss.bind.address.management:10.0.0.210}"/>
   </interface>
  <interface name="public">
       <inet-address value="${jboss.bind.address:10.0.0.210}"/>
  </interface>
  <interface name="unsecure">
      <inet-address value="${jboss.bind.address.unsecure:127.0.0.1}"/>
  </interface>

then I have started the instances (server1 and server2):

./standalone.sh -Djboss.node.name=server1 -c standalone-full-ha.xml

In the server logging i get it right:

07:41:27,019 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (ServerService    Thread Pool -- 63) ISPN000094: Received new cluster view: [server2/web|1] (2)   [server2/web, server1/web]

Apache mod_cluster recognizes the two nodes. In S3 I have granted all the permission to the “wildfly-bucket” to authenticated user, everyone and to myself. I have also tried adding a bucket policy:

 {
    "Version": "2012-10-17",
   "Statement": [
        {
            "Sid": "",
            "Effect": "Allow",
            "Principal": {
            "AWS": "arn:aws:iam::XXXXXXXXXXXXXX:user/laura"
           },
           "Action": [
                "s3:GetObjectVersion",
                "s3:DeleteObject",
                "s3:DeleteObjectVersion",
                "s3:GetObject",
                "s3:PutObject"
            ],
            "Resource": "arn:aws:s3:::wildfly-bucket/*"
         },
       {
            "Sid": "",
            "Effect": "Allow",
            "Principal": {
            "AWS": "arn:aws:iam::XXXXXXXXXXX:user/laura"
            },
            "Action": [
                "s3:ListBucketVersions",
                "s3:ListBucket"
            ],
           "Resource": "arn:aws:s3:::wildfly-bucket"
       }
   ]

}

The user “laura” is in a Group with AdministratorAccess.

I have set the two instances+apache in the same security group and even tried with the same availability zone.

For the security group I have set the following rules INBOUND:

Custom TCP Rule TCP 7600    0.0.0.0/0
Custom TCP Rule TCP 8080    0.0.0.0/0
SSH TCP 22  0.0.0.0/0
HTTP    TCP 80  0.0.0.0/0
All traffic All All 0.0.0.0/0
Custom ICMP Rule    Echo Reply  N/A 0.0.0.0/0
All ICMP    All N/A 0.0.0.0/0
Custom TCP Rule TCP 9990    0.0.0.0/0

OUTBOUND:

Custom TCP Rule TCP 7600    0.0.0.0/0
All traffic All All 0.0.0.0/0

What am I missing?

Can you please help me?

Thank you.
