Interconnect can't connect to the broker

Issue

I use operator deploy broker 7.5 successfully;
Broker 7.5 cluster work well, can produce and consume successfully(Queue name is helloworld).

artemis.cmd consumer --destination helloworld --message-count 76 --url tcp://XX.XX.XX.XX:61616
artemis.cmd producer --destination helloworld --message-count 76 --url tcp://XX.XX.XX.XX:61616

When use interconnect 1.6 basic template deploy and config below. Can't connect to the broker and get below error info.
Config info:

connector {  
  name: broker
  role: route-container
  host: XX.XX.XX.XX
  port: 61616
  saslMechanisms:ANONYMOUS
 }
linkRoute {  
  prefix: helloworld
  direction: in
  connection: broker
}
linkRoute {  
  prefix: helloworld
  direction: out
  connection: broker
}
