Make sure HTTPS is configured correctly. If not it redirects to 404 Not found page.
Note - If HTTPS is not required(in local), configure the url with HTTP for both fields 'web/unsecure/base_url' and 'web/secure/base_url' in core_config_data or in admin. And also disable - web/secure/use_in_adminhtml in core_config_data table.
