Gmail SMTP not working

When I authorize plugin to send emails using gmail account, I get this message –
This app isn’t verified
This app hasn’t been verified by Google yet. Only proceed if you know and trust the developer.

If you’re the developer, submit a verification request to remove this screen.

The thing is I have already verified the app by uploading html file. When i click advanced setting and send the mail anyways I get this message on my website contact page –
Error 404
The page you are looking for does not exist. It may have been moved, or removed altogether. Perhaps you can return back to the site’s homepage and see if you can find what you are looking for.

I followed each and every step of the tutorial. Let me know how to fix this? Do I delete everything and start all over again?
