Answer 1

I was having the same issue. I was running coreos vms in Azure. I found out that all my vms had the same private ip address and different public ip addresses. This usually happens when the vms are part of the same security group, however it was not the case this time. The issue was the my account had reached the max number of resources, so I deleted the resources such as ip addresses, nsg, networks etc and then re-provisioned new vms, they had different private ips and when ran the command everything was fine. My docker version is 1.12.6
