 * Hi,
 * All WordPress, plugins and theme is up to date.
 * After auto update to WP Mail SMTP 2.5 my SMTP settings is reset. I tried to connect
   Gmail SMTP again, with the same cerdentials and updated Authorized redirect URI.
   I saved the settings and then clicked on “Allow plugin to send emails using your
   Google account” button, sign in with chosed Google account as I specifyed in 
   From field (btw this address is different from the admin address in WordPress
   settings) and allow access.
    But after that I redirected to the WP Mail SMTP 
   settings and see the following error message: “There was an error while processing
   the authentication request. Please try again.” [http://prntscr.com/vc2bc9](http://prntscr.com/vc2bc9)
 * I created new OAuth 2.0 Client ID for the same project by your documentation:
   
   [https://wpmailsmtp.com/docs/how-to-set-up-the-gmail-mailer-in-wp-mail-smtp/](https://wpmailsmtp.com/docs/how-to-set-up-the-gmail-mailer-in-wp-mail-smtp/)
   But I receive the same error.
 * Could you help me?
 * Regards,
    Svitozar Lys

 * Hi Svitozar,
 * from what you described, you did everything correctly.
 * Is the ‘wpmailsmtp.com’ domain added to the “Authorized domains” list in the “
   OAuth Consent Screen” section in the Google developer console for your oAuth 
   app?
 * The other thing you could test out is creating a new project with a new oAuth
   app.
 * Let me know how it goes.
 * Take care!
