what do i need to make it work again

Hi @Ferry,

Thanks for getting in touch. I need a little more context to provide a more detailed response. Based on the info you’ve provided here, it’s worth noting that any client with Duo installed needs to be able to contact the Duo API host on port 443. You can find more info here. Duo Authentication for Windows Logon & RDP | Duo Security

I hope this helps!

Hi @Ferry, just a heads up that I linked to the wrong doc in my previous reply. The edited post above has the correct link. Thanks!
