I have been going through this setup for most of the day and I cannot find a way to link my key. I keep ending up in circles at the same page. And I have no idea where to find this key file url? Any help on this would be appreciated. I have my tower running, root passwd set, users created, purchased a key and when I redeemed it using the activation code from the email I have not received any key file url. And when I go to linked keys you can see in the image that there is not key there. I have been up and down the settings and the docs look pretty straight forward yet here I am. Uh, hope someone can help.
