我已经在我的 kubuntu 22.04 上安装了 windscribe，但是当我运行 windscribe 控制台并打开“防火墙”选项时，我失去了互联网连接。
我认为原因可能是我在操作系统中安装了 windscribe，其选项如下：
# sudo ufw enable
Firewall is active and enabled on system startup
# sudo ufw status numbered
Status: active
I have in my OS :
lsb_release -d; uname -r; uname -i
Description: Ubuntu 22.04.3 LTS

x86_64
dpkg -s Windscribe

Description: Windscribe
Windscribe Client.
哪种方法才是正确的，可以允许我使用防火墙访问 Windscribe？
更多信息 ：
我关闭了防火墙，并在操作系统重新启动后检查了我的操作系统：
sudo ufw status numbered
Status: inactive
但当我在 windscribe 上打开防火墙时，我却无法上网。即使我重启了操作系统，情况也是如此。
我与我的互联网提供商的支持人员进行了交谈 - 他们说他们那边没有任何障碍 - 所有问题都只在我这边......
更多信息#2：
现在我在操作系统上已禁用：
# sudo ufw status numbered
Status: inactive
我跑完之后：
sudo ufw enable
我检查了一下：
# sudo iptables -L -nv
