Comment 2 for bug 1304116

I captured a few calls to status as the test was run. This warning looks like the env was changed, not properly restored after the restore:
    WARNING unknown config field "proxy-ssh"

Runnung "Juju ssh 0" fails
    ERROR state/api: websocket.Dial wss://10.0.3.1:17072/: dial tcp 10.0.3.1:17072: connection refused

ssh -i ~/cloud-city/staging-juju-rsa ec2-54-209-166-213.compute-1.amazonaws.com
    ssh: connect to host ec2-54-209-166-213.compute-1.amazonaws.com port 22: Connection timed out

Using the aws console to get the public IP, I tried to ssh with the key tahand was immediately rejected, though that
    ssh -i ~/cloud-city/staging-juju-rsa 54.209.157.232
    Permission denied (publickey)
