Hostname or keys are invalid error


Hi All,

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.


Hi there, we have a knowledge base article for troubleshooting this error. Could you try the suggestions listed there and let us know if it resolves your issue?


My search had returned nothing. This was exactly what I needed. Thanks.


Sure thing. Did you perform a Google or search?
