我刚刚安装了Docker 版本 18.09.0，内部版本 4d60db4在 Windows 10 上。但（由于docker 教程步骤）当我运行：
docker pull hello-world
我面临这样的情况：
Using default tag: latest
Error response from daemon: error parsing HTTP 403 response body: invalid character '<' looking for beginning of value: "<html><body><h
1>403 Forbidden</h1>\nSince Docker is a US company, we must comply with US export control regulations. In an effort to comply with thes
e, we now block all IP addresses that are located in Cuba, Iran, North Korea, Republic of Crimea, Sudan, and Syria. If you are not in o
ne of these cities, countries, or regions and are blocked, please reach out to https://support.docker.com\n</body></html>\n\n"
我找不到问题所在，而且我对 docker 还很陌生。如能得到任何帮助我将不胜感激。
答案1
我找到了，可悲的是，这是因为封锁了“古巴，伊朗，朝鲜，克里米亚共和国，苏丹和叙利亚”等国家的 IP。
