... and you have requested strict checking.

You can check the Jenkins/Git-Host-Key-Verification setting under Global Security...

Jenkins/Git-Host-Key-Verification-Configuration

Obviously you can workaround it by selecting No verification which is not at all recommended though.

In case you want to use Known hosts file verification, you can pre-populate the SSH keys for each server, using the below command (on Linux)...

ssh-keyscan github.com >> ~/.ssh/known_hosts

You have to do that on the user-account that Jenkins is running with.

There is this similar StackOverflow thread "Jenkins Host key verification failed", where other solutions are mentioned, alongside the above.

as mentioned in StackOverflow thread "Jenkins Host key verification failed" don't forget to populate the jenkins user's known_hosts file !

Login before any add to the known_hosts using :

sudo su - jenkins

I have run the following command after logging into the Jenkins container as the jenkins user, to get an automated host key entry in the known_hosts file.

ssh -T git@github.com

And that fixed it.
