Connect failures

[pepone]

How can I debug connection failures, I installed vagrant-tramp from MELPA

I using counsel and the prompt shows /vagrant:ubuntu--xenial64-dev

vagrant global-status --machine-readable

The connection always fails, is the autocompletion inserting the bogus name?

Ssh from the console works fine.
