ActiveMQ replicated levelDB with zookeeper can not visited?

Question

I have 3 zookeeper machines and 3 activemq machines.
here is the configuration.
zookeeper：
tickTime=2000
initLimit=10
syncLimit=2
dataDir=/var/zookeeper/data
clientPort=2181
server.153=192.168.62.153:2888:3888
server.156=192.168.62.156:2888:3888
server.158=192.168.62.158:2888:3888
activemq：

<replicatedLevelDB 
    directory="/opt/apache-activemq-5.11.1/data/leveldb"
    replicas="3"
    bind="tcp://0.0.0.0"                                          
    zkAddress="192.168.62.153:2181,192.168.62.156:2181,192.168.62.158:2181"
    hostname="192.168.62.153"
    zkPath="/opt/zookeeper/leveldb-stores"
    sync="local_disk"
/>

First, I started the three zookeeper machines, then I started the three activemq machines.
the zookeeper machine showed one leader and two flowers.
But when I view the activemq webconsole http://ip:8161, whatever which activemq machine, it can not be visited.
There is no error message in the log, but a warning like this:

SASL configuration failed: javax.security.auth.login.LoginException: No JAAS configuration section named 'Client' was found in specified JAAS configuration file: '/opt/apache-activemq-5.11.1/conf/login.config'. Will continue connection to Zookeeper server without SASL authentication, if Zookeeper server allows it. | org.apache.zookeeper.ClientCnxn
| main-SendThread.

Please help me fixed the problem.

The master has been promoted. But no one to be the slave. So it can not be visited. — sn3009

This warning mustn't interfere in you communication with zk server. You can read that communication go on

"Will continue connection to Zookeeper server without SASL"

Later in you log you should see these following lines who show that communication goes fine :
