Our application worked fine, but today all request returned an auth error:

POST https://oauth2.googleapis.com/token resulted in a `400 Bad Request` response: { "error": "invalid_grant", "error_description": "Bad Request" }

We changed password, generated new refresh token, added new oAuth client, but still became an error

Hi,

Thanks for reaching out to the Google Ads API support and for providing all details. 

I understand that you’ve encountered the error, 'invalid_grant'. Can you please try regenerating your OAuth2 credentials along with the refresh token and see if this behavior persists? Could you verify again, that you followed all steps given in the OAuth web application flow and Oauth desktop application flow? 

Regards,

Yes, I created app in another app and had authenticated with success.

Problem is only with single app
