GCP OAuth consent redirecting to OAuth Overview Page

[Pavle]

When i go to Google Cloud Console > APIs & Services > OAuth consent screen it redirects me to OAuth Overview so I cannot use the Gmail API for my Python program.
I tried multiple browsers and still couldn't access it.

Hi @Pavle,

Welcome to Google Cloud Community!

For troubleshooting, try the following steps to diagnose and resolve the problem aside from trying different browsers:

1. Create a New GCP Project - set up the project to rule out issues with existing project configurations and configure the OAuth consent screen from scratch.
2. Test with a New Gmail Account
3. Use Incognito or Private Browsing Mode
4. Clear Browser Cache and Cookies
5. Verify Two-Factor Authentication (2FA) - 2FA must be enabled for the Google account used in the GCP Console to enhance security and rule out authentication issues. 
6. Test from Multiple IP Addresses - Attempt accessing the GCP Console and OAuth consent screen from different networks such as home Wi-Fi, mobile data, or a VPN.

Refer to these documentations related to configuring OAuth consent screen which you may find helpful:

• Configure the OAuth consent screen and choose scopes 
• Gmail API scopes - This document contains Gmail API-specific authorization and authentication information. Before reading this document, be sure to read the Google Workspace's general authentication and authorization information at Learn about authentication and authorization.

If the issue persists, kindly reach out to Google Workspace Customer Care for further assistance.
