Why do my remote agents always report that the broker URI is invalid?
Asked by Rob_Duff:

No matter what I change my values for the broker URI, it does not seem to work. I tried using the IP address and the host name, and those didn't work. I tried the broker uri and the broker client uri, to no avail. Here is the error I continue to get:

INFO \| jvm 1 \| 2015/01/13 15:50:38 \| 2015-01-13 15:50:38,887 WARN \[Thread-0\] \[BambooActiveMQConnectionFactory\] Broker URI: [tcp://rd-bamboo-s.proddev.XXX:54663?wireFormat.maxInactivityDuration=300000](tcp://rd-bamboo-s.proddev.d2l:54663?wireFormat.maxInactivityDuration=300000) is invalid: [java.net](http://java.net).ConnectException: Connection refused: connect

I've tried telneting from the agent to port 54663 on rd-bamboo-s and I get data back, so it's not a firewall issue. If there's any more information I can provide, please let me know.

WARN \[Thread-0\] \[BambooActiveMQConnectionFactory\] Broker URI: <tcp://localhost:54663?wireFormat.maxInactivityDuration=300000> is invalid: [java.net](http://java.net).SocketTimeoutException: connect timed out

"localhost" doesn't make sense here. Changing Broker client URI to:

failover:([tcp://rd-bamboo-s.proddev.XXX:54663?wireFormat.maxInactivityDuration=300000](tcp://rd-bamboo-s.proddev.d2l:54663?wireFormat.maxInactivityDuration=300000))?initialReconnectDelay=15000\&maxReconnectAttempts=10

fixed the problem.

body: **Thanks Rafael,** but unfortunately I've already been to that page and it doesn't seem to have helped me as much as I had hoped. I've put the defaults back:

Broker URL: <tcp://0.0.0.0:54663?wireFormat.maxInactivityDuration=300000>

[](tcp://0.0.0.0:54663?wireFormat.maxInactivityDuration=300000)Broker client URL: failover:(<tcp://localhost:54663?wireFormat.maxInactivityDuration=300000>)?initialReconnectDelay=15000\&maxReconnectAttempts=10

And still no luck. I'm able to telnet from the agent machine to the server on ports 8085 and 54663 with no issue at all. However, I can't telnet from the server OR the agent machine on the agent's port 54663, which I expect I should be able to do when the agent is running...? All of the firewalls are off on the agent and the server.

The server is Ubuntu 14.04 and the agent is Windows Server 2008 R2.

netstat -an \| findstr 54663 (on the Windows agent) shows nothing, even with the agent running.

netstat -an \| grep 54663 (on the Ubuntu server) shows:

tcp6 0 0 :::54663 :::\* LISTEN

I must admit, I haven't yet enabled DEBUG logging. I'll do that now.

**Przemyslaw,**I do get this on startup of the agent, but eventually the client times out with a (long) Java exception:

javax.jms.JMSException: Connection refused: connect

Caused by: [java.net](http://java.net).ConnectException: Connection refused: connect

Interestingly, even though the server says "There are currently no online remote agents configured on this Bamboo instance", I do see log entries immediately underneath saying "A remote agent is loading on RD-BAMBOO-C.proddev.XXX"
