I have a support case open with DUO Support, Gabby has been extremely helpful but an issue remains with functionality and I’m wondering if anyone has seen a similar problem. The SSTP VPN server is Windows 2012 R2, the DUO AuthProxy version is 2.4.21.
When connecting from an external source, I am consistently getting 4 DUO replies for the one login session. Eventually, the client errors out with a mismatched configuration between the client and VPN server. If I remove DUO from the equation, it works perfectly.
Has anyone had any experience like this? I’ve been thru the RRAS server but I don’t see where the issue may be located and at this point, I’m at a loss.
Any/all help and advice is greatly appreciated.
