ANTs and other gears that use Ubuntu base images were failing because of SSL certificate problems. You can fix this by updating the certificates at the beginning of the gear Dockerfile:
RUN rm /usr/share/ca-certificates/mozilla/DST_Root_CA_X3.crt && \
update-ca-certificates
ENV REQUESTS_CA_BUNDLE "/etc/ssl/certs/ca-certificates.crt"
