Failed to fetch http://deb.debian.org/debian/dists/bullseye-updates/InRelease Unable to connect to deb.debian.org:80

I'm updating one of our apps to 2.0, but I'm having trouble getting it to build. It's bombing out with the following

Step 5/20 : RUN apt-get update -qq   && DEBIAN_FRONTEND=noninteractive apt-get install -yq --no-install-recommends     build-essential     gnupg2     curl     less     git   && apt-get clean   && rm -rf /var/cache/apt/archives/*   && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*   && truncate -s 0 /var/log/*log

I have made some minor changes to the Dockerfile and compose.yml files, but nothing which I think would be causing this problem - I've shared them below anyway.
