Unable to fetch anything from repo.hex.pm using mix

Hi,

I’m unable to fetch anything from Hex using mix commands like deps.update --all or local.rebar or local.hex.

I was trying in 2 different machines using 2 different ISP. There is no special firewalls or network traffic rules.

MIX_DEBUG=1 mix local.hex 
** Running mix loadconfig
** Running mix local.hex
** (Mix.Error) httpc request failed with: {:failed_connect, [{:to_address, {'repo.hex.pm', 443}}, {:inet6, [:inet6], :exbadport}, {:inet, [:inet], :exbadport}]}

Could not install Hex because Mix could not download metadata at https://repo.hex.pm/installs/hex-1.x.csv.

    (mix) lib/mix.ex:323: Mix.raise/1
    (mix) lib/mix/local.ex:126: Mix.Local.find_matching_versions_from_signed_csv!/2
    (mix) lib/mix/tasks/local.hex.ex:56: Mix.Tasks.Local.Hex.run_install/1
    (mix) lib/mix/task.ex:316: Mix.Task.run_task/3
    (mix) lib/mix/cli.ex:79: Mix.CLI.run_task/2

Interesting is fact that Im able to fetch https://repo.hex.pm/installs/hex-1.x.csv using curl or wget.

curl -v https://repo.hex.pm/installs/rebar-1.x.csv

@b3k: How did you install Erlang and Elixir? Maybe try using asdf (version manager).

3

Installed from rpm packages, few weeks ago it was working perfectly (and I didn’t change anything in the meantime). Will try to reinstall whole Erlang ecosystem.

4

It looks like you’re connecting over ipv6, maybe there’s something wrong with your router or ISP’s ipv6 configuration?

5

Solved, after re-installation of all erlang/elixir packages everything starts working. Thanks for help guys!

Just one thing to note. Following:

You should try to call: curl -g -6 -v https://repo.hex.pm/installs/rebar-1.x.csv as your original command is using IPv4 by default and mix is trying to use IPv6 .
