我正在尝试使用包含以下命令的dockerfile构建docker映像。
RUN GIT_CURL_VERBOSE=1 git clone --depth=1 -b master https://code.aliyun.com/SmileYang/adaptive-loadbalance.git
构建docker映像时出现错误：

我尝试在没有docker的情况下运行git clone命令，并且得到以下输出：

这是一个类似的问题：
git clone fails with Operation timed out after 0 milliseconds with 0 out of 0 bytes received
我不知道为什么它在ALPN, offering http/1.1停了下来，看来这是与 SSL 相关的问题。
git版本为 2.11.0
