Unable to git clone from self-hosted GitLab instance with custom port 6022

I am trying to clone a Git repository from a self-hosted GitLab instance that is running on a custom port 6022, but I am unable to do so. Here’s what I’ve tried so far:

  • I have confirmed that the GitLab instance is up and running on port 6022 by checking it with terminal command lsof, netstat, etc.

  • I have created an SSH key and added it to my GitLab account.

  • I have tried to clone the repository using the SSH URL provided by
    GitLab, like this:

    git clone git@mygitlabinstance.com:6022/my-username/my-repo.git
    
  • I have also tried to specify the custom port using the -p flag, like this:

    git clone -p 6022 git@mygitlabinstance.com:my-username/my-repo.git
    

However, both of these methods result in the following error:

Copy code
Cloning into 'my-repo'...
ssh: connect to host mygitlabinstance.com port 6022: Connection refused
fatal: Could not read from remote repository.

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

how can I clone the repository from my self-hosted GitLab instance on port 6022?

this is my docker-compose.yml
