I'd a similar difficulty on Home windows ten. It transpires being due to the aws cli not looking through the internet proxy environment in the Home windows registry. Fastened exact same mistake by location the atmosphere variables HTTP_PROXY and HTTPS_PROXY to the company internet proxy. Hope it helps any individual! https://danteiifcz.activablog.com/28746085/how-much-you-need-to-expect-you-ll-pay-for-a-good-iam997
