Atlassian Bamboo Agent Stuck in Registering


I cannot complete the registration of a Bamboo agent. It just says loading in the logs.

Doing a telnet bamboo-server-host 8085 works but telnet bamboo-server-host 54663 does not. I cannot confirm but this might be the reason why it's not registering.

There are no firewalls that prevent 54663 from being accessed.

Hi @Jack ,

Bamboo server and agents need 2 ports to talk to each other.

  • Port of the Bamboo itself: 8085 by default and when no proxy is used
  • Port of the broker: 54663 by default. You'll find the full broker URL in the Bamboo admin panel (System -> General Configuration)

The traffic between agent and server is bi-directional, initial connections are only sent from agent to server. Responses are sent from server to agent. So, ensure that telnet to 54663 works from your agent.

Hope that helps.


Hi Jey, thanks for the response. Yes, that's my concern. For some reason, 54663 is not accessible from the agent. Although 8085 is accessible.

For some reason, 54663 is not accessible from the agent. Although 8085 is accessible.

You'd need to work with your network admins to make this port accessible from the agent.

I'm confident that you can see the agent loading on the server once 54663 is accessible.


Hi @Jeyanthan I this doesn't work either so I don't think that's the problem.


telnet localhost 54663
Trying ::1...
telnet: Unable to connect to remote host: Cannot assign requested address

This is from the Bamboo server host.
