python - 无法连接到测试服务器。“ERR_CONNECTION_REFUSED”

Question

我是 Django 新手，我正在尝试通过python3 manage.py runserver. 我得到了一切顺利的信息：

Performing system checks...

System check identified no issues (0 silenced).

You have 15 unapplied migration(s). Your project may not work properly 
until you apply the migrations for app(s): admin, auth, contenttypes, 
sessions.
Run 'python manage.py migrate' to apply them.

Django version 2.1.5, using settings 'mytestsite.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

仍然当我尝试http://127.0.0.1:8000/从 Chrome 浏览器连接时，我得到了网站无法访问的信息。我在 Ubuntu 上的防火墙配置：

Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), disabled (routed)
New profiles: skip

To                         Action      From
--                         ------      ----
22/tcp (OpenSSH)           ALLOW IN    Anywhere
8000                       ALLOW IN    Anywhere
Anywhere                   ALLOW IN    127.0.0.1
22/tcp (OpenSSH (v6))      ALLOW IN    Anywhere (v6)
8000 (v6)                  ALLOW IN    Anywhere (v6)

还有什么可能是错的？这是我的第一个设置。感谢帮助。
