Possible issue with OTP23.0-rc3

Hi, I can successfully build an elixir app/release with a docker container using erlang:23.0-rc2 as the base

start of Dockerfile reproduced here:

FROM erlang:23.0-rc2 as elixir

# elixir expects utf8.
ENV ELIXIR_VERSION="v1.10.3" \
	LANG=C.UTF-8

RUN set -xe \
	&& ELIXIR_DOWNLOAD_URL="https://github.com/elixir-lang/elixir/archive/${ELIXIR_VERSION}.tar.gz" \
	&& ELIXIR_DOWNLOAD_SHA256="f3035fc5fdade35c3592a5fa7c8ee1aadb736f565c46b74b68ed7828b3ee1897" \
	&& curl -fSL -o elixir-src.tar.gz $ELIXIR_DOWNLOAD_URL \
	&& echo "$ELIXIR_DOWNLOAD_SHA256  elixir-src.tar.gz" | sha256sum -c - \
	&& mkdir -p /usr/local/src/elixir \
	&& tar -xzC /usr/local/src/elixir --strip-components=1 -f elixir-src.tar.gz \
	&& rm elixir-src.tar.gz \
	&& cd /usr/local/src/elixir \
	&& make install clean

FROM elixir AS app_builder

# The following are build arguments used to change variable parts of the image.
# The name of your application/release (required)
ARG APP_NAME
# The version of the application we are building (required)
ARG APP_VSN
# The environment to build with
ARG MIX_ENV=prod

ENV APP_NAME=${APP_NAME} \
    APP_VSN=${APP_VSN} \
    MIX_ENV=${MIX_ENV}

# Create the application build directory
RUN mkdir /app
WORKDIR /app

# This step installs all the build tools we'll need
RUN apt-get update && \
  apt-get install -y \
    git && \
  mix local.rebar --force && \
  mix local.hex --force




... the rest of the file is app specific and not relevant to the issue

however if I update the base container to rc3 (FROM erlang:23.0-rc3 as elixir) then at the local.hex step I'm now seeing the following:


20:08:53.034 [info]  TLS :client: In state :certify at ssl_connection.erl:1052 generated CLIENT ALERT: Fatal - Decrypt Error

** (Mix) httpc request failed with: {:failed_connect, [{:to_address, {'repo.hex.pm', 443}}, {:inet, [:inet], {:tls_alert, {:decrypt_error, 'TLS client: In state certify at ssl_connection.erl:1052 generated CLIENT ALERT: Fatal - Decrypt Error\n'}}}]}

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

any ideas? 

cheers

Rich
