[Unresolved] Google Services 400 Error

Description of the issue:
Google Services (Gdrive, Gmail and Google Login) do create error message when logging on

How can this issue be reproduced?

  1. Visit site gmail.com
  2. Login with valid credentials

Expected result:
Redirection to email inbox page

Actual result:
400 Error page see Screenshot.


Header: “Error 400 (Bad Request)”

Brave Version( check About Brave):
Version 1.66.110 Chromium: 125.0.6422.60 (Official Build) (64-bit)

Additional Information:
I am not a regular Google services user. In fact I deeply hate using Google services because of their data practices. I am required to use them for work now. I created a new Google account and Immediately had these issues. I could create the account alright, it is set-up and all information and settings are set right. It is just a problem with Brave. From memory I had a similar issue with logging into Sharepoint through Brave some months back.

So I tried multiple known solutions.

Referring to:

1 - Deactivate Brave Shields
2 - Delete Browser Data and Cookies
3 - Add Google Services to Allow Cookies list [B]
4 - Access Site through Incognito Mode [C]
5 - The test shown in [D] I don’t know how to do.
6 - I navigated to brave://settings/cookies as described [E] but I did not find the setting Clear cookies and site data when you close all windows there.

None worked. Issue persists

Partial solution found: I am using a different browser to access the accounts now.
Obviously I am not happy with that though. There can be no way that Brave does not support Google services.
If this issue persists I might need to switch to Firefox.

Did you have on Linux?

I use Windows for the machine where I have the problem on.
