Hi Sachin, The error suggests that you may be using the incorrect OAuth2 credentials for your account. If it was working previously, there might have been a change in the OAuth2 credentials that are being used in your auth.ini file. You could regenerate the credentials using the steps in the setting up OAuth2 authentication <https://developers.google.com/adwords/api/docs/guides/first-api-call#set_up_oauth2_authentication> and getting an OAuth2 refreshToken <https://developers.google.com/adwords/api/docs/guides/first-api-call#get_an_oauth2_refresh_token_and_configure_your_client> guides.
If the issues persist, please provide through *Reply privately to author* the SOAP request and response or any logs so I could investigate the issue further.
