Antigravity CLI 1.1.8 - Account ineligible after successful OAuth authentication

Google Antigravity
1

Hello,

I am experiencing an account eligibility issue with Antigravity CLI 1.1.8.

Environment:

  • Ubuntu 24.04 LTS
  • Antigravity CLI 1.1.8
  • Personal Gmail account
  • Consumer OAuth authentication
  • Local terminal session
  • No Google Cloud CLI dependency involved

Observed behavior:

  1. I start Antigravity CLI.
  2. The browser authentication flow opens normally.
  3. OAuth completes successfully.
  4. The CLI acquires the token successfully.
  5. The CLI recognizes the authenticated personal Gmail account.
  6. A few seconds later, the Antigravity service returns an account eligibility error.

Relevant sanitized log:

consumerOAuth: token acquired

consumerOAuth: authentication completed successfully

consumerOAuth: authenticated successfully as [REDACTED PERSONAL GMAIL]

OAuth: authenticated successfully as [REDACTED PERSONAL GMAIL]

Account ineligible:
Your current account is not eligible for Antigravity.
Verify your account to continue.
Alternatively, try signing in with another personal Google account.

Troubleshooting already completed:

  • Confirmed that Antigravity CLI is installed and starts correctly
  • Confirmed CLI version 1.1.8
  • Confirmed browser OAuth succeeds
  • Confirmed the token is acquired successfully
  • Confirmed the CLI recognizes the correct personal Gmail account
  • Tested both a Google Workspace account and a personal Gmail account
  • Logged out before authenticating with the personal Gmail account
  • Confirmed the CLI was no longer using the previous account
  • Checked the local Antigravity cache
  • Checked Antigravity configuration and log directories
  • Confirmed there are no relevant authentication environment variables
  • Confirmed local commands such as agy --help and agy changelog work normally

The failure therefore occurs after successful authentication, during the server-side account eligibility check.

Could you please confirm:

  1. Whether Antigravity currently has geographic, account-age, rollout, subscription, or invitation-based eligibility restrictions
  2. Whether this is a known issue affecting personal Gmail accounts
  3. Whether any additional account verification or activation step is required
  4. Whether the eligibility state of my account can be reviewed by the Antigravity team

I can provide additional sanitized logs if required. I will not post OAuth tokens, cookies, session identifiers, or other credentials publicly.

Thank you.
