How can handle_info be used to retry the connection?

It seems that the Genserver is down because of HTTPoison failure. In order to allow a retry, the genserver needs to be supervised. The supervisor will catch the failure and try it again. (according to the child spec defined for your genserver)
Please read “https://hexdocs.pm/elixir/GenServer.html#module-how-to-supervise”

rescue HTTPoison.Error or use HTTPoison.request and handle {:error, :timeout} return value.
