Duo proxy one user problem


#1

Hello,
I have a Duo working with Palo alto vpn , palo alto uses a duo proxy to use the AD auth.
I have only one user that is getting an error when trying to enter the portal.
Same user works for login to his computer and from the same computer when i use a deferent user it works.
How can i debug it ? , is there a cache or setting that can cause such a problem?
Thanks
