Downtime of Elixir app

There are no datapoints since the server is not responding.
Neither the app is not accessible during this time, all the endpoints are down.

For more details the app deployed as a docker image with Traefik in front for domain and htts certificate.

I am excluding Erlang VM as the culprint so the only things I can think of are:

  • server restarts
  • networking issue
  • traefik proxy not being able to forward the requests

What else can it be?
