F5 APM change password AD stops on athenticating

We have setup an APM Radius two factor with securenvoy to logon to VDI. We have some problems when user is asked for change their password. The new login box comes and we type a new password, after this I can see the traffic to and from our AD server and F5, but the login box just says "autheticating...." for a long time, after 2-3 minutes it times out. When we try to log in again, the password is changed. What do we need to change in our setup so the user is forwarded right after the password change, and dont have to disconnect and login with 2 factor one more time?
