主机操作系统：
阿里云ECS Anolis OS 8.8 ANCK 64位
问题描述：
执行
curl -sfL https://rancher-mirror.rancher.cn/rke2/install.sh | sh -
报错信息如下：
[INFO] finding release for channel stable
[INFO] using 1.28 series from channel stable
Rancher RKE2 Common (stable) 0.0 B/s | 0 B 02:00
Errors during downloading metadata for repository 'rancher-rke2-common-stable':
- Curl error (28): Timeout was reached for https://rpm.rancher.io/rke2/stable/common/centos/8/noarch/repodata/repomd.xml [Connection timed out after 30000 milliseconds]
Error: Failed to download metadata for repo 'rancher-rke2-common-stable': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
ping rpm.rancher.io 也不通。
补充说明：不仅阿里云的网络环境，在本地电脑也无法访问
https://rpm.rancher.io/rke2/stable/common/centos/8/noarch/repodata/repomd.xml
有什么好办法解决网络不通的问题吗？
预期结果：
能够正常执行安装脚本。
