Hi,
This process *works*

I just tested it again successfully.
My parameters :
- url:
www.insee.fr/en/statistiques/serie/telec...eFin=3&anneeFin=2018
- localPath: d:/temp/result.zip
I suppose the download you are trying to achieve may have something particular. For example : proxy connection required ? authentication required ?
Please provide more details so that we can help you
