Hey Santosh,

So the tunnel client that Elastic Bamboo uses is trying to connect to the address that is configured as your Base URL at Bamboo Administration >> Overview >> General Configuration >> Base URL.

It looks like there is an AWS ALB at that address (judging by the cookie in the response) and that ALB is getting an invalid response from the backend application it's forwarding HTTP traffic to.

Assuming that the ALB is getting that invalid response from the Bamboo Server -- there should be more information in the Bamboo Server logs when the 502 gets logged agent side that might suggest what went wrong. You should tail them while the agent attempts to connect to see you can learn anything more. The log is located at:

• <bamboo-home>/logs/atlassian-bamboo.log

Alternatively, you might want to consider bypassing the AWS ALB entirely and keep the traffic from the Elastic Agent that comes over the tunnel, local. Try the resolution in the below knowledge-base article and see if that helps:

• Elastic Agents remain in pending and don't connect
