错误：[SSL：TLSV1_ALERT_PROTOCOL_VERSION] tlsv1警报协议版本

Question

我一直在努力解决这个问题，需要帮助。 所以我正在为项目使用django-cookiecutter + docker。 将docker容器部署到服务器后，该应用程序运行正常。

但是当尝试通过cirlceci进行更改时，我在部署阶段遇到此错误

    Checking connection to Docker...
    Docker is up and running!
    To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env production
    Building postgres
    ERROR: SSL error: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:661)
    Exited with code 1

我曾尝试过重新生成证书，但仍无所事事，我敢肯定，这是我遗漏的琐碎事情。 知道为什么会这样吗？
