I am trying to complete the Set Up Your Salesforce DX Environment module.  I have successfully created a test DX account and have installed the CLI (Windows x64 bit).  However, when I try and complete the next step, by entering sfdx force:auth:web:login -d -a DevHub into the command prompt, the browser (Chrome) asks me to login which I enter my credentials, but then when I click the Login button, the browser appears like it's going to a new page, but then it displays a page with a "This page isn't working localhost didn't send any data." error and the command prompt displays "ERROR: self signed certificate in certificate chain."

Does anybody know what I am doing wrong on getting to complete this step of the module?  Thanks.
