Multiple applications on different vm are not able to connect ,only the first one getting connection is able to connect

Hi,

I am using the trial version amq-broker-7.2.0 for evaluation purpose. My infrastructure works perfectly well with Activemq. I have 3 application hosted on a different machine with different ip. All communicating with each other with amq. But this is not working.
When I start the servers all connected to the same amq , the first one getting connection gets connected while others give
Caused by: ActiveMQNotConnectedException[errorType=NOT_CONNECTED message=AMQ119007: Cannot connect to server(s). Tried with all available servers.]
on the server and not able to create a session. Is this limitation with the trial version or some configuration to allow multiple remote client connections to the same broker?
