daphne with ssl over ip6

Using Django
1

Hello,

i have difficulties to run django with daphne on a dyndns-server with a ssl certificate. This server has only ip6.

I tried many things, now:
daphne -e tcp6:80 -e ssl:443:privateKey= .../privkey.pem:certKey=.../fullchain.pem name_of_project.asgi:application

but it’s not working. I can access it with ip4, but not with ip6.

sudo netstat -tulpen | grep -v 127.0.0.1 return:
tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 0 202080 37564/python
tcp6 0 0 :::80 :::* LISTEN 0 202081 37564/python

What must I do for using daphne with ip6 and https? Thanks
