SSH error when new kit/device created in QtCreator

I get this error when I click the "Test" button in Options->Devices in QtCreator

On the device side, I see this in /var/log/auth.log:

I'm running QtCreator in a Ubuntu VM session running on windows. I can ssh into the remote device in a terminal using password with no issue, from either the VM session or putty running on windows.

The remote device is a pi zero w running Stretch Lite. I've been using the same VM session and QtCreator for other rpi kits (but Wheezy/Jessie, not Stretch) for several years without issues.

I've googled the error text and see others reporting this issue, but I couldn't find a workaround.

Maybe it would work with a key? But, where to find doc on how to do that? (but, I can also ssh with key (no password) from a terminal without issue).

Any workaround suggestion would be greatly appreciated!

Added after 42 minutes:

I deleted the device and recreated it.

Now, it's working.

The first time I didn't have all the fields correct. However, I edited them and they were exactly what worked when I deleted then recreated the device.

So, for what it's worth, maybe something gets saved (white space?) when you edit the fields that can't be seen.

But, I'm working now.
