Return wrong username and permission when using SSH key

Summary

I am admin with highest permission in my gitlab and owner of every project but I cannot clone/pull/push code by using SSH keys.

When I run ssh -Tv git@gitlab.domain in my terminal, it returns

debug1: channel 0: new [client-session]

debug1: Requesting no-more-sessions@openssh.com

debug1: Entering interactive session.

debug1: client_input_global_request: rtype hostkeys-00@openssh.com want_reply 0

You can see, it welcome another people who is a developer in my Gitlab server.

Therefore, when I clone a repo, I get

GitLab: The project you were looking for could not be found. fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

Noted

• Other member has got a their permission and only me encounter the problem.
• Before I got the problem, I try the article as below to try work with SSH keys via port 443. And now i can work with https without input username/ password.

https://about.gitlab.com/2016/02/18/gitlab-dot-com-now-supports-an-alternate-git-plus-ssh-port/

Edit ~/.ssh/config as below:

Host gitlab Hostname gitlab.domain User git Port 443 PreferredAuthentications publickey IdentityFile ~/.ssh/id_rsa IdentitiesOnly yes

After that, I comment out the config in ~/.ssh/config to work with SSH but It returns error as above. I can do everything with Https :(
