为什么 curl 似乎无法在代理后面工作？

当通过代理使用 curl 时，

curl -O -fsSL https://storage.googleapis.com/tensorflow-serving-apt/tensorflow-serving.release.pub.gpg -v -k -x http://xxx.xxx.xxx.xxx:8080

我遇到了如下错误。我该如何解决？

我还尝试了一些其他的东西……

  1. 无需代理，它就能工作......

    curl -O -fsSL https://storage.googleapis.com/tensorflow-serving-apt/tensorflow-serving.release.pub.gpg -v -k

  2. 当使用下面的代理访问一个特定的 URL 时，它可以工作......

    curl -O -fsSL https://get.docker.com/gpg -v -k -x http://xxx.xxx.xxx.xxx:8080

  3. 当使用代理访问其他 URL 时，它会返回相同的错误。

    curl -O -fsSL https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png -v -k -x http://xxx.xxx.xxx.xxx:8080

  4. -v4添加了诸如、、或之-v6类的选项，但并没有解决问题。--http1.0--http2.0
