I’ve try to do more tests with ssl_hello_world in cowboy(v1.0)  and various Erlang/OTP versions.

If ErlangOTP < 17.0, http/https works fine.
If ErlangOTP >= 17.1(17.1.x,17.2 in github), http works fine but with https the same errors appeared.

When I edited ranch_accepter.erl > line 40 
	{error, Reason} when Reason =/= closed -> 
	to
	{error, Reason} ->
,
https work and app was normally quitted.

When I printed, Reason == closed.
