404 during OAuth callback

[geoHeil]

Following along with https://github.com/jupyterhub/jupyterhub-deploy-docker I created https://github.com/viennadatasciencegroup/jupyterhub which hosts a Jupiter hub at https://hub.vdsg.at/hub/login

However, when clicking on the login button

[I 2017-10-24 05:26:19.722 JupyterHub oauth2:82] OAuth redirect: 'https://hub.vdsg.at/hub/oauth_callback'
jupyterhub | [I 2017-10-24 05:26:19.724 JupyterHub log:122] 302 GET /hub/oauth_login?next= → https://github.com/login/oauth/authorize?state=eyJzdGF0ZV9pZCI6ICJjNDgzZjZlMjk3MDE0NTRhYjE4ZjgyY2MxMjMxZTY0MiIsICJuZXh0X3VybCI6ICIifQ==&response_type=code&client_id=&redirect_uri=https://hub.vdsg.at/hub/oauth_callback (@::ffff:78.46.228.137) 3.06ms

the logs only show an redirect and GitHub itself returns an 404

The IP of the spawner is already set via docker-DNS

• https://github.com/viennadatasciencegroup/jupyterhub/blob/master/jupyterhub_config.py#L46
• https://github.com/viennadatasciencegroup/jupyterhub/blob/master/docker-compose.yml#L30

To me the redirect URL with spaces and empty client_id parameter as well as binary (@::ffff:78.46.228.137) looks a bit weird.
