Hi Holly, This is a host key verification problem. You need to configure a strategy as documented in [GitHub - jenkinsci/git-client-plugin at git-client-4.0.0](https://github.com/jenkinsci/git-client-plugin/tree/git-client-4.0.0#ssh-host-key-verification). Regards, ---

Thank you Allen. Does this document also good for GitLab? I am using GitLab. Thank you - Holly ---

Yes, the documentation applies for GitLab and all other git providers. When the documentation is specific to a git provider, it will list the specific git providers. Documentation is most easily read from the [plugins.jenkins.io/git-client page](https://plugins.jenkins.io/git-client/#plugin-content-ssh-host-key-verification) > **[Git client](https://plugins.jenkins.io/git-client/#plugin-content-ssh-host-key-verification)** > > Utility plugin for Git support in Jenkins ---

Thank you slide. Yes, I am able to find set up location. Allan/Mark - [plugins.jenkins.io/git-client page](https://plugins.jenkins.io/git-client/#plugin-content-ssh-host-key-verification), how could I use this document ? what strategy I can use to configure? My current set up by default Known hosts file. When I run command (git ls-remote -h [git@mcdasatest07.isd.lacounty.gov]:jenkins/ampsoaapplication.git HEAD) from server, it keep asking me the password and not recognized the password. mcdasatest07:/var/cache\>git ls-remote -h [git@mcdasatest07.isd.lacounty.gov]:jenkins/ampsoaapplication.git [git@mcdasatest07.isd.lacounty.gov](mailto:git@mcdasatest07.isd.lacounty.gov)’s password: Permission denied, please try again. ---

You might try this video tutorial from Darin Pope: [![](https://europe1.discourse-cdn.com/flex013/uploads/jenkins/original/2X/e/e1dd4ebe451c4d693ecb4a08a2cb18431a01a3e8.jpeg "How to Add Git Credentials in Jenkins") ](https://www.youtube.com/watch?v=HSA_mZoADSw) The message from command line git indicates that you’re either providing the wrong ssh private key credential or you’re providing a username / password credential instead of providing an ssh private key credential. The git repository URL `git@mcdasatest07.isd.lacounty.gov]:jenkins/ampsoaapplication.git` is a URL that tells command line git to authenticate with `ssh` using an ssh private key. If you’ve not defined an ssh private key credential, then you need to do that. If you’ve defined a username / password credential instead of an ssh private key credential, then you need to change to use `https` instead of `ssh` for the git repository URL. > [@hollychen](#): > > Allan/Mark - [plugins.jenkins.io/git-client page](https://plugins.jenkins.io/git-client/#plugin-content-ssh-host-key-verification), how could I use this document ? what strategy I can use to configure? My current set up by default Known hosts file. Based on the message from `git ls-remote`, you don’t need to change the ssh host key verification strategy. It is already working as expected. Your [original post](https://community.jenkins.io/t/jenkins-not-able-to-connect-to-git-repository/8707/1) had this message: > [@hollychen](#): > > Failed to connect to repository: Command “git ls-remote -h [git@mcdasatest07.isd.lacounty.gov]:jenkins/ampsoaapplication.git HEAD” returned status code 128: > stdout: > stderr: Host key verification failed. > fatal: Could not read from remote repository. If you’re still seeing that message, then you need to adjust your host key verification strategy. The message `Host key verification failed` means that you do not have a working host key verification strategy because host key verification is failing. ---

Thanks Mark. I created a SSH key for another application on my local. Do I need to create another SSH key for this application or I can share the same SSH key with that application. Is there any meeting discussion in our community? that will be a big help and speed up the issue resolve process. Appreciate your help. ---

I created a SSH key for another application on my local. Do I need to create another SSH key for this application or I can share the same SSH key with that application. Each application need to have it’s own git set up? Please advise. ---

> [@hollychen](#): > > Do I need to create another SSH key for this application or I can share the same SSH key with that application. > Each application need to have it’s own git set up? It is your choice whether you use the same ssh key or a separate ssh key. The separate ssh key adds some management overhead (need to track it, etc.) but then allows that ssh key to be removed from the account or rotated without breaking any other use of that repository. ---
