问题：我无法访问我的 gunicorn api从我的本地计算机。
我有一个 Python 应用程序，使用 gunicorn 在 CentOS 服务器（否） nginx 或者类似的东西）。它正在发挥作用：

[xxx@xxx xxx]$ poetry run gunicorn api.main:app -b 0.0.0.0:5000 -w 4 -k uvicorn.workers.UvicornWorker
Using python3 (3.9.5)

我有一个用于测试的简单端点，当我从服务器本身调用它时，它正在工作，通过调用 localhost 和服务器地址：

[xxx@xxx xxx]$ curl localhost:5000/get_test
"Thanks for calling!"
[xxx@xxx xxx]$ curl myserveraddress.com:5000/get_test
"Thanks for calling!"

我可以从windows计算机ping服务器，一切正常：

C:\>ping myserveraddress.com

Pinging myserveraddress.com [xx.xx.xx.xx] with 32 bytes of data:
Reply from xx.xx.xx.xx: bytes=32 time=51ms TTL=55
Reply from xx.xx.xx.xx: bytes=32 time=51ms TTL=55
Reply from xx.xx.xx.xx: bytes=32 time=51ms TTL=55
Reply from xx.xx.xx.xx: bytes=32 time=51ms TTL=55

但我无法从我的计算机访问此终结点（我收到超时）：

C:\>curl myserveraddress.com:5000/get_test
curl: (7) Failed to connect to myserveraddress.com port 5000: Timed out
``` `firewalld` 规则似乎不是问题，因为它们都是公开的：

[xxx@xxx xxx]$ sudo firewall-cmd --get-default-zone
public
[xxx@xxx xxx]$ sudo firewall-cmd --get-active-zones
public
interfaces: ens192

但我特别在规则中添加了端口5000：

[xxx@xxx xxx]$ sudo firewall-cmd --add-port=5000/tcp --permanent
success
[xxx@xxx xxx]$ sudo firewall-cmd --reload
success
[xxx@xxx xxx]$ sudo firewall-cmd --query-port=5000/tcp
yes

每次手术后，我都会重新开始 `gunicorn` 服务器。
我也查过了 `iptables` （但据我所知 `firewalld` 使用 `iptables` 下面），但整个输出由所有和任何地方组成，例如：

Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere anywhere ctstate RELATED,ESTABLISHED
ACCEPT all -- anywhere anywhere

我还可以做些什么来允许流量进入我的web服务器？或者只是调试，问题是什么？
