气流在首页加载时卡住

Question

我是Apache Airflow的新手，所以我已经按照下面的命令安装并启动了Airflow。

airflow webserver -p 8080

返回消息看起来像气流成功启动。

[bank@RHEL01 airflow]$ airflow webserver -p 8080
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Airflow 1.10 will be the last release series to support Python 2

此后，我尝试打开Airflow UI，但在进入首页时出现卡住的情况，如下所示。

如何解决此问题？

有关差异端口8082的更多信息，因为我在Virtualbox 6上使用了Redhat Linux VM。然后，我为访问SSH（2522-> 22）和Airflow（8082-> 8080）配置了端口转发）来自主机的访客。我可以远程登录所有已配置的端口。
