Registering PJSIP endpoint via sipML5

Hello,

I am new to asterisk and having problem registering pjsip endpoint via sipML5.
asterisk console:-
== WebSocket connection from ‘192.168.1.190:34091’ for protocol ‘sip’ accepted using version ‘13’
[Aug 4 11:18:22] NOTICE[6485]: chan_sip.c:28117 handle_request_register: Registration from ‘"101"sip:101@192.168.1.190’ failed for ‘192.168.1.190:34091’ - Wrong password

however i had successfully registered a sip user, means no problem with http.conf and rtp.conf…

pjsip.conf
