If I run the package-test-server.py and I try to connect from a browser with http://0.0.0.0:8000/archive-contents, I get ERR_ADDRESS_INVALID. But that I have the same error if I try to open: http://xx.xx.xx.xx:8000/archive-contents with xx.xx.xx.xx being my current IP address. I get the file only if I connect to http://127.0.0.1:8000/archive-contents. So I suspect that it is a default setting of the firewall in Windows 10. The python server script test/automated/data/package/package-test-server.py runs explicitly on 127.0.0.1, so why not using this address in the test? What does using 0.0.0.0 brings here in the package-test-update-archives-async test?
