Antigravity App sign in error

Google Antigravity
1

When trying to sign in to the Antigravity App (both Antigravity IDE and Antigravity 2.0), I get an error.
After scanning the QR code on my iPhone 17, I tried sending the message it asks me to send, and it says, “Couldn’t deliver.”
This only happens with this specific verification shortcut number. All other numbers I try to send a message/SMS to work.
I have no other way to verify, even though I have my iPhone 17 logged into this account, with 2FA enabled, and my phone verified.

Hello @contin

  • For issues where the browser succeeds but the app hangs, you can patch the authentication token serialization by adding BigInt.prototype.toJSON = function() { return this.toString(); }; to the top of the main.js file located in the application’s resource directory.
  • If you are stuck in a Pro/Ultra subscriber login loop, try forcing an account sync by logging into the Gemini CLI via your terminal with your subscribed account and sending a prompt such as “I want to use Antigravity with this account.”
  • For SMS verification failures, clear the application caches located in %APPDATA%\Antigravity and %USERPROFILE%\.gemini, or try scanning the verification QR code using an iPhone. If you encounter DNS resolution errors, change your network adapter’s DNS to 8.8.8.8.
  • Finally, ensure you are running the latest versions: Antigravity 2.0 (2.6.0), Antigravity IDE (2.1.1), and Antigravity CLI (1.1.11).

If none of these steps resolve the issue, can you share the exact error code or a screenshot of where the login process stops?

I’ve tried to login via the Antigravity CLI (Since Gemini CLI referenced no longer accepts 0auth from Google accounts), and I was blocked by the exact same issue, asking for verification, as shown in the following screenshots:

Once inside the verification URL, I get the same QRCode to scan with my phone, requesting me to send a SMS message to a given short number, which my phone says it’s not able to deliver the mssage

(Again, I can send messages to any numbers, just not the short ones from Google)

There’s no option to try to verify in other way. My account has 2fa, age verification, recovery email verified.

Other Google accounts work fine.
