how about:

>          Issue Type: Bug
>            Reporter: Vilius Šumskas
>            Priority: Major
>
> Let's say there is a simple Artemis HA master/slave shared storage cluster 
> with such configuration:
>  
> {noformat}
> <connectors>
>    <connector 
> name="artemis-master">tcp://internal-cluster-dns-1:61616</connector>
>    <connector 
> name="artemis-slave">tcp://internal-cluster-dns-2:61616</connector>
> </connectors>
> {noformat}
> The cluster is using static discovery.
>  
> Factory on internal clients are using:
> {noformat}
> (tcp://internal-cluster-dns-1:61616,tcp://internal-cluster-dns-2:61616)?ha=true&reconnectAttempts=30&useTopologyForLoadBalancing=false{noformat}
> Those internal clients can successfully connect to the cluster and failover 
> works as expected.
>  
> However if there is also external clients which use external DNS/IP address 
> of the cluster the topology doesn't return correct DNS name and the failover 
> fails.
> {noformat}
> (tcp://external-cluster-dns-1:61616,tcp://external-cluster-dns-2:61616)?ha=true&reconnectAttempts=30&useTopologyForLoadBalancing=false{noformat}
> {noformat}
> org.apache.activemq.artemis.core.remoting.impl.netty.NettyConnector: 
> AMQ214033: Cannot resolve host java.net.UnknownHostException: 
> internal-cluster-dns-1{noformat}
