docker拉图像时出现x509错误

我创build一个新的虚拟机并安装docker.But它不能拉任何图像。 我的VM是Centos7。

像这样：

docker pull hello-world 

这是我的错误报告，

 Error while pulling image: Get https://index.docker.io/v1/repositories/library/hello-world/images: x509: certificate is valid for 192.168.0.81, not index.docker.io 

我不知道“192.168.0.81”是什么，每个拉动命令都得到相同的报告。

请帮助我，谢谢。

这是我的docker信息：

如果您位于代理之后，请确保您configurationdocker以使用此代理。 https://docs.docker.com/engine/admin/systemd/#httphttps-proxy
