$ curl -vik --resolve www.amd.com:443:173.222.181.51 https://www.amd.com/
* http2 error: Remote peer returned unexpected data while we expected SETTINGS frame. Perhaps, peer does not support HTTP/2 properly.
http 1.1
$ curl --http1.1 -vik --resolve www.amd.com:443:173.222.181.51 https://www.amd.com/
可以連上
8.8.8.8 給的 IP
$ curl -vik --resolve www.amd.com:443:103.239.61.56 https://www.amd.com/
可以連上
如果用 cloudflare warp 就正常沒問題
只用 1.1.1.1 才有問題
因為有問題的 IP 是 akamai 的, 應該是 akamai 部分 edge http2 有問題
