How to fix Account Setup, Login, and Model Disappear error in Antigravity?

You’re stuck outside Antigravity after an agent error loop: retries failed, clearing auth/cache didn’t help, and now login shows “There was an unexpected issue setting up your account. Please try again later.” In some cases, the model list also vanishes right after login.

This issue usually starts with an agent entering a loop (e.g., in Planning mode), then showing “We can’t process this right now. Start a new chat or try again.” After multiple retries and a cache/auth clear, you may get locked out with: “There was an unexpected issue setting up your account. Please try again later.”

Some users also report that the model picker goes blank (models disappear) immediately after login. This often points to IP/region throttling or a server-side incident tied to your auth session.

If your session also showed agent crashes before the lockout, see this quick helper on recurring agent failures: agent terminated errors.

Solution Overview

Aspect	Detail
Root Cause	Temporary backend/auth incident compounded by IP/geo rate-limiting; clearing caches can invalidate session and trigger stricter checks; region gating can hide models.
Primary Fix	Change your network (disable VPN, switch to another ISP or mobile hotspot), then do a clean site re-auth.
Complexity	Easy
Estimated Time	5–15 minutes

Step-by-Step Solution

1) Quick network reset to bypass IP/geo throttling (primary fix)

Turn off any VPN/Proxy/Enterprise tunnel.
Switch networks:
Connect to a different Wi‑Fi or a mobile hotspot.
If possible, power-cycle your router to pick up a fresh IP.
On macOS, refresh name resolution and your DHCP lease:
Flush DNS:

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

Renew DHCP (replace "Wi-Fi" if your interface name differs):

networksetup -renewdhcp "Wi-Fi"

Confirm your public IP changed:

curl -s https://ifconfig.me

Open Antigravity and sign in again.

2) Force a clean, safe re-auth (without wiping all Google data)

In Chrome (recommended):
Open Antigravity.
DevTools > Application > Clear storage > select all checkboxes > Clear site data.
Application > Service Workers > Unregister any service workers for the Antigravity origin.
Or, in Settings: chrome://settings/siteData?searchSubstr=antigravity and Remove all site data for the Antigravity domain.
Sign out of your Google account, then back in:
Google Account device activity → Sign out of old sessions for this browser/device.
Sign back in at Antigravity.
If you use aggressive content blockers (uBlock, Pi‑hole, NextDNS), disable them for the Antigravity domain and retry.
If login still fails, do the same steps in a fresh Chrome Profile or a different browser (Edge/Safari/Firefox).

3) Fix “Models disappeared” after login

Hard refresh the app (Shift+Reload or Ctrl/Cmd+Shift+R).
Disable VPN/Proxy that forces a region not supported by the models you expect.
If you’re in a restricted geography, connect via a supported region only if policy allows. See current coverage: Model and region availability.
Sign out/in after the network change to refresh entitlements.
If the model list is still empty, switch to a different mode or create a new project/chat, then return to Planning mode.

4) If it’s a backend incident, wait and verify

Sometimes this is purely server-side and resolves globally once rolled out.
Check public dashboards for signs of auth or account issues:
Google Workspace Status Dashboard
Google Cloud Status Dashboard
Try again in 15–30 minutes on a known-good network profile.

Alternative Fixes & Workarounds

Use a different Google account temporarily

Sign out, then log in with another Google account to continue urgent work.
Migrate back once your primary account works again.

Start from a fresh browser profile

Create a new Chrome Profile and sign in to Antigravity there; this avoids stale IndexedDB/service workers and conflicting extensions.

Temporarily switch transport

If you must stay on the same ISP, tether through your phone hotspot to bypass local ISP throttles while the main connection stabilizes.

Troubleshooting Tips

Limit retries when you see “We can’t process this right now.” Excessive retries can trigger IP throttling.
Make sure system time and timezone are correct; skewed clocks break auth tokens.
Test without extensions:
Chrome → New Incognito Window (Ctrl/Cmd+Shift+N) → No extensions by default.
If you use corporate SSO, confirm the organization hasn’t restricted access to Antigravity or specific models.
Capture error details:
Open DevTools → Network → find the failed request → copy the Request ID and response code; useful for support.

Best Practices

Keep a backup browser/profile specifically for AI tools to isolate cache/issues.
Avoid clearing all Google auth unless instructed; prefer per-site data removal.
Refrain from rapid-fire retries; wait 1–2 minutes between attempts.
Maintain a known-good network path: disable VPN/proxy when testing access.
Bookmark region availability updates to avoid the “models disappeared” surprise: Availability reference.

Final Thought

The fastest path is simple: switch networks, clear site data, and re-auth. If models still vanish or login blocks persist, it’s likely a short-lived backend issue—wait a bit and try again with a clean session. These steps should get you back into Antigravity quickly and prevent repeat lockouts.
