I'm using the personal edition of Duo Security and am now running into an issue where when I try to setup Duo MS RDP application on a server, I am getting the error "The shotname or keys you have entered are invalid. Please verify that they match those given to you by Duo Security". I've confirmed that they are an exact match (I used copy/paste).
Has anyone else run into this issue? I've been able to successfully add this application many times before so not sure what's causing this failure now.
