Remote Agents stopped working after bamboo upgrade to 9.0

[Rakesh Yadav]

We upgraded the bamboo to version 9.0. After the upgradation process, the remote agent stopped working.

Also, the link to download the remote agent jar file shows an internal server error. 

Below is the error log while launching remote agent.

Hello @Rakesh Yadav,

It seems there is something else going on with your Bamboo instance. Your agent fails to retrieve information from the server with an HTTP 500 error:

INFO | jvm 1 | 2022/09/17 02:20:50 | com.atlassian.bamboo.agent.bootstrap.RemoteAgentHttpException: Response: [HTTP/1.1 500 ] received after manifest retrieval request.

Please check your Bamboo Server on <bamboo-home>/logs/atlassian-bamboo.log for any messages or stack traces that may give you a clue of what's going on.

If you can't locate anything obvious, please open a ticket with Atlassian at https://support.atlassian.com/contact.

Please do not post any private information here. This is a public forum and may expose your internal information.
