Cloning via SSH from a group - Project not found

Hi,

First, thanks for the great work!

I am trying to clone a repository via ssh but I cannot get it to work... I have already looked at some open/closed issues but none of them solved my problem.

Part of my docker-compose.yml:

gitlab:
  expose:
    - "443"
  ports:
    - "8443:22"
  nextworks:
    - proxy
    - default
  environment:
    - GITLAB_SSH_PORT=8443

The proxy networks is used for the web interface because I am using a reverse proxy in front - It works fine.

I try the following methods to clone:

$ git clone https://gitlab.example.com/group/project.git # Works fine
$ git clone ssh://git@gitlab.example.com:8443/group/project.git 
Cloning into 'project'...
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.

However it works fine for user project...

Start with docker-compose.yml and reproduce the SSH clone using GITLAB_SSH_PORT=8443, comparing the failing group path with the working user project path. Trace the SSH URL and group-project lookup behavior, then verify that cloning the group repository succeeds without changing the working HTTPS path.
