Asterisk REGISTER pjsip 403 Forbidden

Guy can you help me to know what problem is it?

Here is my config:
pjsip

[102]
type=endpoint
aors=102
auth=102
disallow=all
allow=ulaw,alaw,gsm,g726,g722
context=from-internal
callerid=102 <102>

[102]
type=auth
auth_type=userpass
username=102
password=102

[102]
type=aor
max_contacts=1

here is my sip.conf

[starcom]
type=peer
host=173.193.144.207
context=starcom-in
insecure=port
disallow=all
allow=ulaw
qualify=yes
dtmfmode=rfc2833
sendrpid=yes

[general]
nat=force_rport,comedia
directmedia=no
context=public
allowoverlap=no
udpbindaddr=0.0.0.0:5060
tcpenable=yes
tcpbindaddr=0.0.0.0
transport=udp
srvlookup=yes
disallow=all
allow=ulaw
rtpstart=10000
rtpend=60000
localnet=172.31.21.61/16
localnet=172.17.0.2/16
localnet=192.168.1.3/16

Unless you know what you are doing, you should not use chan_sip and pjsip at the same time. sip.conf is used for the older chan_sip.
Do you really want to use both?
