@Leemoonsoo I have investigated further.
See also this related issue https://github.com/npm/npm/issues/2866.
It seems that, at the moment, there is only one workaround to address the
`ECONNRESET error (HTTP/1.1 407 Proxy authentication required)` that is using
HTTP requests, like I did with npm configuration:
```
npm config set registry "http://registry.npmjs.org/";
npm config set strict-ssl false
```
Unfortunately Bower is currently unable to handle the HTTP request, so you
will always hit the authentication error. I have also tried Fiddler with and
without `Automatically Authenticate` option and changing the User-Agent with no
success.
The strange thing is that if I open one of the failing request with
Chrome/curl I can see the JSON repsonse:
```
curl https://bower.herokuapp.com/packages/json3
% Total % Received % Xferd Average Speed Time Time Time
Current
Dload Upload Total Spent Left
Speed
100 62 100 62 0 0 81 0 --:--:-- --:--:-- --:--:--
82{"name":"json3","url":"https://github.com/bestiejs/json3.git"}
```
Another alternative would be to setup and use a local Bower repository, but
it is quite expensive solution.
