Hi Yair,

Thank you for reaching out. It looks like you've got an authorization issue. Can you confirm you're connected to the Internet and that you properly set up the config file for all the OAuth2 credentials? Please re-generate the OAuth2 credentials following this guide. Let me know if you have any further questions.

Thanks and regards,
Xiaoming, Google Ads API Team
