YUM更新错误 EC2 Could not retrieve mirrorlist https...
Could not retrieve mirrorlist https://amazonlinux-2-repos-us-west-2.s3.dualstack.us-west-2.amazonaws.com/2/core/latest/x86_64/mirror.list error was
12: Timeout on https://amazonlinux-2-repos-us-west-2.s3.dualstack.us-west-2.amazonaws.com/2/core/latest/x86_64/mirror.list: (28, 'Failed to connect to amazonlinux-2-repos-us-west-2.s3.dualstack.us-west-2.amazonaws.com port 443 after 4982 ms: Connection timed out')```
以下是我已经检查过的内容:
1. NACL和安全组已经打开了入站端口80和443
2.出站NACL和安全组已经对所有TCP开放
3.互联网网关正确附加
4.已为此EC2分配了公共、弹性IP,仍然无法运行。
不确定我还缺少什么?
