Debian repo not working?

Hi everybody. Just tried to set up the repos for apt, but running into problems.

My sources.list
deb http://packages.elastic.co/logstash/2.2/debian stable main

When issuing an apt-update, apt will start and the it tries to connect endlessly to the elastic.co repo.

100% [Connecting to packages.elastic.co (2406:da00:ff00::b849:ba57)]

I added the key manually via apt-key add.

Any help appreciated..

Ah, the process run into an timeout. Apt states:

Mh, if I add

184.72.244.137 packages.elastic.co

in my /etc/hosts everything works like a charm. Seems like the IPv6 host is down?

I added that to mine, and the IP it was trying to use changed to something else...
