i trying set ha clustering on amazon web service wildfly-10. standalone-ha.xml configuration is

... <subsystem xmlns="urn:jboss:domain:jgroups:4.0"> <channels default="ee">     <channel name="ee" stack="s3ping"/> <channels> <stacks>        ...                 <stack name="s3ping">        <transport type="tcp" socket-binding="jgroups-tcp" diagnostics-socket-binding="jgroups-diagnostics"/>            <protocol type="s3_ping">                <property name="access_key">                    <%= @s3_access_key %>                </property>                <property name="secret_access_key">                    <%= @s3_secret_access_key %>                </property>                <property name="prefix">                    <%= @s3_bucket %>                </property>                <property name="timeout">                    60000                </property>            </protocol>            <protocol type="merge2"/>            <protocol type="fd_sock" socket-binding="jgroups-tcp-fd"/>                          <protocol type="fd"/>            <protocol type="verify_suspect"/>            <protocol type="barrier"/>            <protocol type="pbcast.nakack"/>            <protocol type="unicast2"/>            <protocol type="pbcast.stable"/>            <protocol type="pbcast.gms"/>            <protocol type="ufc"/>            <protocol type="mfc"/>            <protocol type="frag2"/>        </stack> </stacks> </subsystem> ... 

with similar configuration able cluster wildfly 8 , wildfly 8.2. wildfly 10, not able succeed it.

also have added <distributable/> web.xml.

on console getting warn saying;

[org.jboss.protocols.pbcast.gms] (msc service thread 1-1) node1: join(node1) sent node1 timed out (after 3000 ms), on try 1 

and continues on try 10.

what fault , how can fix it.

thanks.
