Hello Antigravity / Google Team,
Since Antigravity IDE isn’t working, I have to report the issue here. Google team, please resolve this as our workflow is being disrupted.
I would like to report an issue I encountered while attempting to log in to Antigravity IDE. The login flow was blocked by Google’s automated query protection, preventing me from authenticating.
ENVIRONMENT
- Application: Antigravity IDE 1.22.2
- OS: Windows 11
- Date/Time: 2026-04-13 at 14:03 (UTC+3, Istanbul)
- Log session: 20260413T140326
STEPS TO REPRODUCE
- Launched Antigravity IDE.
- Clicked “Sign in with Google” to initiate the OAuth flow.
- Antigravity opened the Google OAuth URL in the default browser (accounts.google.com/o/oauth2/v2/auth).
- A localhost callback server was started on port 64602 to receive the OAuth token.
- Google returned an HTML error page instead of the authorization code.
Google returned the following error response to the OAuth callback:
“We’re sorry… but your computer or network may be sending automated queries. To protect our users, we can’t process your request right now.”
This caused a cascade of errors in the application logs:
- auth.log: “Error confirming user for service”
- Antigravity.log: “Failed to get OAuth token: state syncing error: key not found”
- Antigravity.log: “failed to set auth token”
- Antigravity.log: “Cache(userInfo): Singleflight refresh failed”
The localhost server was shut down immediately after the error, and the login session was terminated.
ADDITIONAL CONTEXT
- I was not using a VPN at the time.
- No excessive login attempts were made prior to this session.
- The browser had an active Google session.
- No other network anomalies were observed.
- The error appears to originate from Google’s bot-detection system flagging the programmatic OAuth request initiated by the desktop application.
RELEVANT LOG EXCERPTS
From auth.log:
[14:03:46] Login URL opened: https://accounts.google.com/o/oauth2/v2/auth?…
[14:03:55] Error confirming user for service: <Google ‘Sorry’ HTML page>
[14:03:55] Localhost server stopped
From Antigravity.log:
[14:03:46] Failed to get OAuth token: state syncing error: key not found
[14:03:46] failed to set auth token
[14:03:46] Cache(userInfo): Singleflight refresh failed
Please investigate why the standard desktop OAuth flow is being flagged as automated traffic. This makes it impossible to log in to Antigravity under normal conditions.
Thank you for your time.
Best regards,
İbrahim
