SSH credential fails in discovery but passes credential test

We have an SSH credential that works to login from command line to target host. It also passes the 'test credential' test from the instance to the same target host. It works to discovery several thousand other hosts. But it fails in actual discovery job.


The ECC queue shows: SSH authentication or connection failure and the system is not classified

Any chance of checking the logs on the ubuntu box? (should be in /var/log/auth.log) - they may show you what's happening server-side.



The only other thought is that "connection failure" - what do you get is you manually run that command?   Credential test works find so it's definitely not the key issue.

Hi! I had the same issue.


If you have an aged instance (deployed initally before Eureka)




Add this Configuration Parameter to your MIDservers as theat parameters is not set in the default




mid.ssh.use_snc   (set it to true)
