Problem
The elastic agents are not coming up and the Bamboo server logs register the following log message:
1
Timeout has expired for waiting for tunnel to instance [i-HASH], terminating [Tunnel ##.##.##.##:1234 - (##.##.##.##:26224) - 0.0.0.0:54663] Error: Connection refusedResolution
Make sure the tunnel port 26224 is open and accessible.
Troubleshooting steps:
Run the following from the Bamboo host:
telnet elastic-agent-ip-here 26224nmap -p 26224 elastic-agent-ip-herenetstat -nat | grep LISTEN
Are there any security settings in EC2 that may have blocked that port?
Open the ports as needed depending on the output of the above.
Contact the Atlassian Support sharing your findings if this issue persists.
