make: *** [docker-build] Error 1

I have increased the poetry time out as you can see by ENV POETRY_REQUESTS_TIMEOUT=300 but still the problem is there and it is not stable; I wonder how to circumvent and make it more stable

the error comes from => ERROR [6/8] RUN poetry install --no-dev --no-interaction --no-ansi
