Hi @Soju.Jamuul 

By the looks of that error message you have configured "aaa + certificates", if you only wish to authenticate using DUO double check your authentication method is AAA only. Post screenshots of your configuration if required.

Hello Rob Ingram

it was by default AAA Only, and for VPN I only chose the SSL Only, as shown in the screen shots.

My RADIUS server is 192.168.1.50 ,and My FTD  is 192.168.2.15.
