You are locked out of Google Antigravity after an agent loop. The app now shows There was an unexpected issue setting up your account. Please try again later when you try to sign back in.

Antigravity login blocked after agent loop and cache clear

You were in Planning mode when the agent stalled and returned We can’t process this right now. Start a new chat or try again. After multiple retries, a new chat failed immediately. Logging out and clearing Google authentication caches led to a persistent account setup error on login. This often points to IP reputation or regional gating combined with a temporary backend issue. If you also see related issues like models not appearing after login or quota messages, see this quick explainer on account setup login problems.

Fix your Antigravity login now

Step by Step Solution

Step 1 Confirm service health and avoid retry storms If there is an active incident, repeated retries can extend your block window. Check the relevant product status page for outages. If an outage is reported, wait for the fix and try again later. Step 2 Fully sign out then use a clean browser context If you previously wiped all Google caches, use a fresh Chrome profile instead of the same one to avoid partial cookies or broken tokens. Step 3 Reset network to change public IP This is the most effective action for the reported case. You want a new public IP or egress path. Try in order
  • Switch to a different trusted network home office mobile hotspot
  • Power cycle your modem or router to receive a new WAN lease
  • Use a reputable VPN endpoint in a supported region then retry sign in
On macOS you can also renew your lease and flush DNS 
# Flush DNS cache
sudo dscacheutil -flushcache
sudo killall mDNSResponder


Optional renew DHCP on a given service name, e.g. Wi-Fi


List services

networksetup -listallnetworkservices

Renew DHCP for Wi-Fi

sudo ipconfig set en0 DHCP
Verify your current public IP and geolocation before and after network changes Step 4 Clear site specific cookies for the app only Prefer targeted cleanup instead of deleting all Google auth data
  • In Chrome address bar enter
chrome://settings/siteData
  • Search for the Antigravity domain and remove its data
  • Close all app tabs then reopen and sign in
Step 5 Reauthenticate carefully
  • Open the Antigravity app and sign in once
  • If you get the same error, stop retries for 15 minutes then attempt again on the alternate network
If you also encounter quota messages such as Critical quota errors during sign in or model selection, see this short note on quota related failures.

Alternative Fixes and Workarounds

Use a different device or OS user
  • Sign in from another Mac user profile or a second machine to rule out profile corruption
Disable extensions and content filters
  • Temporarily disable ad blockers privacy extensions proxies or corporate filters that may interfere with Google auth redirects
New Chrome profile
  • Create a new Chrome user profile and sign in there which avoids residual tokens
Keychain cleanup on macOS only if needed
  • Open Keychain Access search for Google related web passwords for the app domain remove just those entries then retry sign in
Wait for backend remediation
  • The thread confirms a technical issue acknowledgment. If the network reset does not help, the fix may be server side and you should wait and retry later
For errors that point to version mismatches or feature rollout delays, review this quick reference on version related problems.

Troubleshooting Tips

  • Confirm system date and time are correct automatic time skew can break OAuth flows
  • Test without VPN or corporate proxy then with a trusted VPN endpoint to compare outcomes
  • Try both mobile data hotspot and home broadband to see if one IP range is gated
  • Check for regional restrictions if you are traveling or your IP geolocation changed
  • Use a single Google account during sign in and avoid rapid account switching
  • If errors persist capture time zone public IP and any request IDs from the error and share with support

Best Practices

  • Keep a secondary network option mobile hotspot for recovery when auth is IP gated
  • Favor targeted cookie cleanup per site over clearing all Google account data
  • Avoid rapid retries after an error and space attempts by 10 to 15 minutes
  • Maintain a clean browser profile dedicated to critical workspaces
  • Monitor service status during incidents before performing invasive local fixes

Final Thought

The fastest fix here is a network change to obtain a new public IP, followed by a clean sign in. If it still fails there is likely a temporary service issue, so wait for the backend fix and retry later.
