Health Monitor Authentication issue!

Hi Experts,

I want to use authentication for https monitor:

I configured the monitor as follow, and applied it to the member 10.10.3.38:

(tmos) list ltm monitor http TEset
ltm monitor http TEset {
    defaults-from http
    destination *:http
    interval 5
    ip-dscp 0
    password $M$Di$qDUaY70YZlWkuZZAqqD2uw==
    send "GET /default1.asp HTTP/1.1\r\nHost: 10.10.3.38\r\nConnection: Close\r\n\r\n"
    time-until-up 0
    timeout 16
    username admin
}

BUT the status of the member is always down, even I didn't specify a receive sting!!!!!!!

SSLDUMP:

when I tried to do ssldump I've got the output as follow:
