Ubuntu 带有外部nginx的自托管GitLab在尝试克隆项目时出现502错误

VPS，清晰的Ubuntu 18.04 LTS，2核，4 GB RAM，25 GB磁盘

安装nginx和乘客

在子域中安装GitLab

禁用GitLab内置的nginx，切换到外部nginx

我根据GitLab文档完成了这三点

在/var/opt/gitlab上为git用户添加授权权限，并安装ruby dev&&nodejs

之后，GitLab出现在子域中，我定义了管理员密码，一般来说，web版本看起来工作正常

但我无法从GitLab克隆项目，它会出现502错误：

$ git clone https://git.myserver.com/root/tock.git   Cloning into
'tock'...   remote: GitLab is not responding   fatal: unable to access
'https://git.myserver.com/root/tock.git/': The requested URL returned
error: 502

当我尝试克隆时，以下条目出现在var/log/gitlab/nginx/gitlab\u access.log的内置nginx日志中：

81.30.208.16 - - [03/May/2021:13:51:42 +0300] "GET /root/tock.git/info/refs?service=git-upload-pack HTTP/1.1" 502 24 "-" "git/2.29.2.windows.2"

81.30.208.16 - - [03/May/2021:13:56:02 +0300] "GET /users/sign_in HTTP/1.1" 200 15487 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.93 Safari/537.36"

当我在浏览器中打开git.myserver.com页面时，在var/log/gitlab/nginx/gitlab_access.log的内置nginx日志中会出现以下条目：

81.30.208.16 - - [03/May/2021:13:51:42 +0300] "GET /root/tock.git/info/refs?service=git-upload-pack HTTP/1.1" 502 24 "-" "git/2.29.2.windows.2"

但是位于var/log/nginx/access.log和var/log/nginx/error.log的“普通”（预装、外部）nginx的日志为空

也许内置的nginx没有完全禁用
