Hello!

Are you seeing this error when attempting to SSH into a device? If so, have you SSH’d into another device using the same IP address? (i.e. another mangoh/fx30 over USB?)

If so, look at your ~/.ssh/known_hosts file and remove the line for the old device at that IP address (the default is 192.168.2.2).
