I restarted multiple times. I tried all options available "Known Hosts Key Validation", "Manually Provided key Validation", etc..still get the same/similar errors. I have the below messages in my WebLogic logs for both..The first five are for nodes configured with "Known Hosts Key Validation" while the last one is for "Manually Provided Key validation"... I am able to login at server level using same ssh keys, but when invoking the same using same credentials via Jenkins, it fails.
