[closed] Jenkins Host key verification failed

 I have a problem with jenkins, setting "git", shows the following error:

Failed to connect to repository : Command "git ls-remote -h https://person@bitbucket.org/person/projectmarket.git HEAD" returned status code 128:
stdout:
stderr: fatal: Authentication failed

I have tested with ssh:

git@bitbucket.org:person/projectmarket.git

This is error:

Failed to connect to repository : Command "git ls-remote -h git@bitbucket.org:person/projectmarket.git HEAD" returned status code 128:
stdout:
stderr: Host key verification failed.
fatal: The remote end hung up unexpectedly

I've also done these steps with "SSH key".

Login under Jenkins

sudo su jenkins

Copy your github key to Jenkins .ssh folder

cp ~/.ssh/id_rsa_github* /var/lib/jenkins/.ssh/

Rename the keys

mv id_rsa_github id_rsa
mv id_rsa_github.pub id_rsa.pub

but still not working git repository in jenkins.

thanks by help!.
