Hi I have deployed Jenkins 2.117 war file onto WebLogic 12.2.1.2 as a webapplication and I am able to login to the application. I want to add additional nodes (remote servers) and would like to launch them using SSH, I have ssh key setup configured between the master where the WebLogic hosting Jenkins is running and remote servers and able to connect via shell. But when I try to do the same from within the application, I keep getting the below error message on the console output. I tried searching web and other support sites, and it seems this was fixed sometime in 2017 in older releases i.e in SSH Slave Plugin 1.20. I still keep getting the same and I see the plugin version installed is 1.26 for SSH Slave.
Any help or pointers in right direction is appreciated. Thanks Warning: no key algorithms provided; JENKINS-42959 disabled [04/20/18 08:39:05] [SSH] Opening SSH connection to XXX.abc.com:22.
