Fianlly. I have found the reason
use command "show log all"

Because my account's password had a special character "%"
on webui It from "%" became to "R2 verbose" That is the wrong password,that why radius server reject the client's request.
on cli It just "%" No doubt that it can pass the authetication
When I change the password .there is no "%" in it .then it pass..on webui
But how did that happed? we can't use "%" in out password in 8.5???
Is there any special character we can't use ?????
