从远程dockerregistry中拉出图像失败，超时exception

我在本地部署了一个映像，如下所示

[root@user]# docker tag hello-world localhost:5000/hello-world [root@user]# docker push localhost:5000/hello-world The push refers to a repository [localhost:5000/hello-world] a02596fdd012: Pushed latest: digest: sha256:a18ed77532f6d6781500db650194e0f9396ba5f05f8b50d4046b294ae5f83aa4 size: 524 

步骤1：

 [root@user]# docker pull localhost:5000/hello-world Using default tag: latest latest: Pulling from hello-world Digest: sha256:a18ed77532f6d6781500db650194e0f9396ba5f05f8b50d4046b294ae5f83aa4 Status: Image is up to date for localhost:5000/hello-world:latest 

它工作正常

我试图从远程机器拉相同的图像

第2步：

 [root@user]# docker tag hello-world server-ip:5000/hello-world 

当我在做docker推，我得到以下错误

 communication error occurred: \"Operation timed out\"\r\n</FONT>\r\n</TD></TR>\r\n<TR><TD>\r\n<FONT face=\"Helvetica\">\r\nThe Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time. 

我已经在远程机器的dockerregistry中添加了服务器IP，但仍然看到这个错误

以下是服务器和客户端docker信息 –
