Error: Getting Unreachable hosts

Hi am getting this Unreachable hosts issue when trying to run the crawl from the Docker image by using following command

docker run -it --env-file=./config/development/dev.env -e "CONFIG=$(cat ./config/config.json | jq -r tostring)" algolia/docsearch-scraper

I’m getting following issue

Traceback (most recent call last):

algoliasearch.exceptions.AlgoliaUnreachableHostException: Unreachable hosts

Do you have any idea how to fix this issue ?

Thanks
