I have resolve this Issue:–
Go to the API Console: https://code.google.com/apis/console/
Select the Api Access at the left Panel:-
After that go to Client ID for web applications and click edit setting in the right side then a popup is open.
Change the link for Client ID for web applications to https://mysite.com/wp-content/plugins/wordpress-social-login/hybridauth/?hauth.done=Google
after that save all the changes.
