I am unable to log into Antigravity using my Jio-provisioned Gemini Pro Google account. After completing the Google OAuth flow successfully, the app silently redirects me back to the login screen with no error message displayed.
Other Google accounts on the same device and installation log in without any issue—confirming this is specific to my Jio-provisioned account and not a local or network problem.
Console Logs (Developer Tools)
I investigated using the built-in developer console and found the following errors repeating on every login attempt:
POST https://127.0.0.1:[port]/proxy/unleash/frontend — 404 Not Found
Unleash: Fetching feature toggles did not have an ok response
[AntigravityUnleashService] [object Object]
After OAuth completes, the app calls AntigravityUnleashService to resolve feature flags via the local Unleash proxy. This returns 404, meaning my account is either not present or not yet flagged as eligible in Antigravity’s Unleash backend. Without a successful flag resolution, the session setup aborts and the app loops back to the login screen.
Since Claude Sonnet and Opus are officially listed as supported models within Antigravity, this provisioning failure is blocking access to those models as well—not just Gemini.
I have also already tried the following without success:
Verified the account is in a supported region
Confirmed Gemini Pro subscription is active
Tried reinstalling / clearing app data
Posted on X and Reddit — no resolution
