我是新来的多库和nginx服务器，我正在尝试在本地设置服务器Linux Ubuntu 20.04出于测试目的而不是使用诸如赫茨纳（云）或 DigitalOcean（已包含多库图像这是比我需要的旧版本的 Dokku），这可能会导致不必要的财务费用。
更准确地说，我正在尝试在我的/etc/hosts文件中设置域地址，例如（更新这与dokku.me域）：
127.0.0.1 localhost
188.x.xx.xxx domain.com
10.0.0.2 dokku.me
通过遵循这个Dokku 设置教程并向其传递以下命令之一：
$ dokku domains:set-global localhost
$ dokku domains:set-global domain.com
但是一旦我执行以下命令（为了显示创建的djangotutorial应用程序）：
$ dokku config:show djangotutorial
...我得到这个作为输出：
=====> djangotutorial env vars
NO_VHOST: 1
从那里我在提到的教程中正常执行所有内容，直到执行以下命令（推送到远程服务器）：
$ git push dokku main
...我收到以下消息：
ssh: connect to host domain.com port 22: Connection timed out
fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.
