Access to localhost was denied in Chrome if manual proxy is set in preferences

Access to localhost was denied if manual proxy configuration is set under preferences, when running tests in Chrome only (FF and IE works!).

In other scenario, if no proxy is set (or -Use system proxy config), then it’s not possible to connect to (but access to localhost in Chrome works!)
How to resolve this?

Any feedbacks, comments?

Good evening sir…

When I try to run Test suite in command prompt I’m getting this error “Access is denied.” What should I do?
