Hello @tabrez ahmad,

Can you run the same SSH connection from the Agent command line using the 'ssh' command?

If 'ssh' works, please open a support ticket on https://support.atlassian.com/contact as we'd be interested to debug the net.schmizz.sshj class.

Hi Eduardo,

We tried running the script on the server from our remote agent and it was successful and there was no SSH connection issue. 

Thanks,

Tabrez

We're having the same issue with longer build jobs. Recently upgraded Bamboo from 8.0.4 to 9.1.0 and all of our most imporant builds are now failing even with SSH Keepalive set to 5 or 10 seconds on SSH Tasks.
