远程PC无法通过Traefik代理的GitLab执行git clone问题

我遇到了GitLab仓库克隆的问题：

• 能正常访问GitLab的Web界面；
• 在rudak_traefik_network网络的容器内、Docker服务器本机上都可以顺利执行git clone操作，但远程PC无法完成；
• Traefik仪表盘显示所有路由状态正常，包括针对gitlab.roger的TCP路由HostSNI(gitlab.roger)；
• 已经在GitLab中配置好远程PC的SSH密钥，且该密钥在容器内可以正常使用，但在远程PC执行git clone git@gitlab.roger:roger/test-project.git时，终端会提示输入密码，输出如下：

git clone git@gitlab.roger:roger/test-project.git
Cloning into 'test-project'...
git@gitlab.roger's password: 

（服务器名为roger，我认为这不是问题）

以下是我的GitLab和Traefik配置：

GitLab Docker Compose配置 #
