This is what I got from my symfony debugger. Unless I disable errors for notices I can't use the library. Any idea the issue on that line?

After reading some of the other comments I got this to work by setting the errors for this part to ignore notices (error_reporting(E_ERROR | E_WARNING | E_PARSE);) and then I upgraded to curl with http2 support. For others that might need the commands in DOCKER this is what I did.

#Install curl again but with HTTP-2 Protocol Support Now
RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y tmux wget htop
RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y
g++ make binutils autoconf automake autotools-dev libtool pkg-config
zlib1g-dev libcunit1-dev libssl-dev libxml2-dev libev-dev libevent-dev libjansson-dev
libjemalloc-dev cython python3-dev python-setuptools

RUN git clone https://github.com/tatsuhiro-t/nghttp2.git
WORKDIR nghttp2
RUN autoreconf -i
RUN automake
RUN autoconf
RUN ./configure
RUN make
RUN make install

#Upgrades to latest curl for http2 support
WORKDIR ~
RUN apt-get update && apt-get build-dep -y curl
RUN wget http://curl.haxx.se/download/curl-7.46.0.tar.bz2
RUN tar -xvjf curl-7.46.0.tar.bz2
WORKDIR curl-7.46.0
RUN ./configure --with-nghttp2=/usr/local --with-ssl
RUN make
RUN make install
RUN ldconfig

This made it work for me :)
