docker-machine version 0.11.0, build 5b27455

I have a number of remote hosts that I need to enable VPN to access. After updating to the latest version of Docker Toolkit I'm now getting extra errors when below the host list for those that are in a timeout state.

The errors do not appear when when docker-machine is able to reach all hosts.

$ docker-machine ls

I am also having this issue on version docker-machine version 0.12.2, build 9371605, it appears to happen right after I create a multi node env. Driver = vmwarevsphere

Could this be related to that fact that the default timeout is set to low? lsDefaultTimeout = 10 My command always seems to error out after 10 seconds, in larger environments I could see this taking longer that 10 seconds.

same error after I created the 3rd node

I was able to get rid of these error by removing the references to remote instances that no longer exist using docker-machine rm <instance name>. Once I did that, docker-machine ls returned the list of available nodes without any errors
