(CaseClauseError) no case clause matching: {:error, :badarg}

Hi there,

I'm trying to get Tortoise to run for publishing to a MQTT server. If I simply try in iex: {ok, _pid} = Tortoise.Connection.start_link( client_id: "HelloWorld", server: {Tortoise.Transport.Tcp, host: "localhost", port: 1883}, handler: {Tortoise.Handler.Logger, []})

I'm getting:

Does anyone have an idea what's wrong here?

I have the same problem! Interesting fact: on my Windows WSL (ubuntu 18.04) everything works fine, but on native ubuntu 18.04 I have the same error.

Hi; just to let you know—I am in the middle of moving to a new country, so that is why I haven't been responsive lately. I hope I will get back to it soon—sorry for the wait.

It seems that you are running Elixir 1.6.4; can you try a more recent version and see if the problem persist ?

And sorry for the late reply; life has been eventful lately on my end.

Hi, I've fixed the problem by updating Erlang/OTP 19 to Erlang/OTP 21

[gausby]

Awesome ! I'll close the issue then. I'll bump the minimum required Elixir version soonish.
