@Festum Can you post debug logs?

[festum]

@pecigonzalo I found the problem is caused by default OpenSSHd as default ssh client in SysEnvPath. Solved by changing it to Portable Git's ssh binary.

Thanks for reporting back, i think another user just had the same issue, i will look to submit a fix to upstream docker-machine
