If you have eneterd correct details in https://console.cloud.google.com/apis/credentials?project=project_name , then wait for few minutes as sometime's it take time to update the details.

Also please double check your url in google console, it must be
http://yourwebsite/signin-google

Above answer may not work for all users so few points to consider about this issue

  1. If you're using Google+ javascript button, then you have to use postmessage instead of the actual URI,aslo you need to specify this in 2 places (if you are using the web-app-server-flow). One is in the g-signin button on the javascript. The other is in the signet authorization client in your server code.
  2. Make sure to check the protocol "http://" or "https://" as google checks protocol as well.
  3. Using trailing slash (http://example.com/) in Authorized Redirect URIs and not using trailing slash (http://example.com) as actual URL, or vice-versa
  4. Error may also occur if actual site has www and on google cloud console it is registered without www
