acme.sh(ZeroSSL) + xray(trojan) + nginx 在 Linux 下证书错误

昨天换掉了一键脚本用 docker compose 重新配置了 vps 的代理，配置完成后发现在 Linux 下使用 curl 来查看伪装站点的话会报错，错误信息如下：

 $ curl -I https://proxy.example.xyz
HTTP/1.1 200 Connection established

curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

而且 Linux 下 Clash 节点配置必须要开启 skip-cert-verify 选项后才可以正常使用，但是在 macOS 上就正常，curl 可以正常返回站点信息，Clash 也不需要开启 skip-cert-verify ，这种情况是什么问题导致的？

xray 的证书配置如下：

"streamSettings":{
  "network":"tcp",
  "security":"xtls",
  "xtlsSettings":{
    "serverName":"proxy.example.xyz",
    "alpn":[
      "h2",
      "http/1.1"
    ],
    "certificates":[
      {
        "certificateFile":"/etc/acme.sh/proxy.example.xyz.cer",
        "keyFile":"/etc/acme.sh/proxy.example.xyz.key"
      }
    ]
  }

}
