Client auto update failure

By default the Dockerized client is set up to automatically update the Meterian client it is built with. As such the latest version of the client is downloaded and cached right before the scan.

Should this operation fail the following error is printed

$ meterian-docker
Updating the client...
Unexpected error: client update failed via url: https://www.meterian.io/downloads/meterian-cli.jar
Please ensure connections to https://www.meterian.io/downloads/meterian-cli.jar are permitted from the Docker container

As per error message you should ensure connections to the download URL is functioning on your end.

Should this not be enough, to further diagnose what is causing the curl call to fail you can run this command

$ docker run --rm -it --entrypoint "/usr/bin/env" meterian/cli curl "https://www.meterian.io/downloads/meterian-cli.jar"
