Google OAuth is only working for some google accounts

[KirstenS]

We would like to use Google OAuth for login and registration to our service. It works but only for some google accounts. For most of the time the user isn't redirected back to the login portal.

We don't understand why it does not work properly? Maybe you could help us?

Hi @KirstenS,

Welcome to the Google Cloud Community!

Just to verify, is your application in "Testing" or "In Production" status? If it's "In Production" mode, I see two common issues with these:

1. It's possible the redirect URI isn’t set up right in the Google API Console. This detail is important for making sure users get sent back to your app correctly after signing in.

2. There could be issues related to how the OAuth flow has been coded within your service. This aspect also warrants a thorough review to ensure it aligns with the expected OAuth standards and practices.

You may check this document for more information - Redirect URI Overview.

I hope this helps. Thank you.

If Google OAuth is only working for some Google accounts, ensure that the affected accounts have the necessary permissions and that your OAuth configuration is accurate. Verify client IDs, scopes, and redirect URIs, and check for any specific restrictions on the affected accounts.

Debugging logs and error messages can provide insights into the issue. If problems persist, consider reaching out to Google Cloud Support or consulting the Google Identity Platform documentation for troubleshooting steps.
