title: trouble connecting to AWS Lightsail via SSH with keys other than default
body: <p>I have downloaded the default private key and am able to connect via SSH with no problem using that private key. In my Lightsail instance, I went to the SSH Keys tab, created a new key pair and downloaded the new private key (savng it in the correct location on my local machine with proper permissions). However, i am unable to connect using that new private key. Here is the output I get from the command:  <code>ssh -v  -i ~/.ssh/test.pem me@x.x.x.x</code> </p>

  <p>I've got to be missing a step on the SSH Keys screen, but I can't seem to figure out what it would be. Can anyone help?</p>
