daphne always listening on 0.0.0.0

[Arnau Bria]

Dear all,

I start daphne like:

bin/daphne \

  -b 127.0.0.1 -e ssl:8001:privateKey=/.../cert.pem:certKey=/opt.../privkey.pem \

  NewRweb.asgi:application

but daphne keeps listeinig on 0.0.0.0:

2021-09-13 13:39:45,785 daphne.cli   INFO     Starting server at ssl:8001:privateKey=/.../cert.pem:certKey=.../privkey.pem, tcp:port=8000:interface=127.0.0.1

2021-09-13 13:39:45,791 daphne.server INFO     Listening on TCP address 127.0.0.1:8000

and

# netstat -putan|grep 8001

tcp        0      0 0.0.0.0:8001            0.0.0.0:*               LISTEN      11161/python

how can I restrictc daphne to localhost?

my daphne version is 

python 3.8.2

daphne 3.0.1

channels 3.0.2

TIA,

Arnau
