Why my Bower remote repository does not work?

Bower have changed their Registry URL from https://bower.herokuapp.com to https://registry.bower.io.

All Artifactory versions released prior to the fix are using the old registry URL by default.
This causes all "bower install" commands to fail due to "404", e.g.:

$ bower install angular        $ bower ENOTFOUND     Package angular not found

In order to work around this issue, in the remote Bower repository configuration change the registry URL from https://bower.herokuapp.com to https://registry.bower.io.
