Please re-check below points that is may be responsible behind 401 error.

1. Make sure to have Google+ API enabled Please use Google Developers Console to activate the API for your project.

2. Project name should be sort Navigate to Consent Screen section in your Google API console (from the sidebar at left), change product name and save changes.

3. Product name should not same as project name The product name can be set in the Consent screen section of the Google Developers Console for your project. Look under APIs & auth in the left navigation and select Consent screen. You need also to set your email address in the box above the product name.

After one of the above code, restart your app. I hope this will help you.
