How to fix Antigravity stuck at loading agent?

Users report Antigravity gets stuck on the message One moment, the agent is currently loading, and even the in app feedback spinner never finishes. This guide gives the fastest fixes to get your agent loading again.

Antigravity stuck on “One moment, the agent is currently loading”

Hero
Antigravity opens but never progresses past the loading banner. Feedback submission is also frozen on submitting, suggesting a stuck session, cached state, or a background service that did not initialize. For a quick checklist and common causes, see our detailed tips here: troubleshooting steps for a stuck agent.

Step by Step Solution

1. Hard refresh and re authenticate
  • Reload the page bypassing cache.
– Windows or Linux: Ctrl F5 or Ctrl Shift R – macOS: Shift Command R
  • Sign out of Antigravity, fully close the tab or app, then sign back in.
This resets a stuck session token that often causes the loading banner. 2. Clear Antigravity site data in the browser
  • In Chrome or Edge: open Settings, Privacy and security, Site settings, View permissions and data stored across sites, search for antigravity, remove site data and permissions.
  • Or open DevTools, Application tab, Storage, clear Local Storage, Session Storage, and IndexedDB for the Antigravity origin.
  • Reopen Antigravity and sign in again.
3. Restart the background Agent Manager A stalled local helper can freeze the frontend. Restart it after closing Antigravity.
  • Close Antigravity completely.
  • If you have a system tray icon for an agent helper, exit it.
  • Reopen Antigravity.

  • Open a private window and sign in to Antigravity.
  • If it loads, disable extensions one by one to find the blocker, especially privacy filters that can break websockets.
5. Check network, VPN, and firewall
  • Turn off VPN and custom DNS briefly.
  • Try a different network such as a mobile hotspot.
  • Corporate firewalls that intercept TLS can block the websocket handshake used by the agent loader.
6. Flush DNS and restart the system
  • Windows Command Prompt as Administrator:
– ipconfig /flushdns
  • macOS Terminal:
– sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
  • Linux with systemd:
– sudo systemd-resolve –flush-caches
  • Reboot and try again.
7. Update Antigravity or your browser
  • Ensure you have the latest Antigravity build or the latest stable browser.
  • Outdated runtimes can fail on recent authentication or websocket changes.

Alternative Fixes and Workarounds

Use a different browser or profile
  • Try Chrome, Edge, or Firefox with a fresh profile to rule out corrupt profile data.
Wait and retry after a brief cooldown
  • If a backend incident is in progress, waiting ten to fifteen minutes can help once services recover. Refresh and sign back in.
Use the desktop app if the browser is failing
  • If you have a desktop build, try that version. If the desktop build is failing, switch to the browser version to confirm scope of the issue.

Troubleshooting Tips

  • Confirm the websocket connects
In DevTools, Network tab, filter for ws and confirm a 101 Switching Protocols response. If it fails, inspect any proxy or content filter in use.
  • Look for console errors
Open DevTools, Console tab, and note any errors related to authentication, CORS, or blocked resources. These often point to an extension or firewall.
  • Try a clean device
Testing Antigravity from another machine helps isolate device specific corruption.
  • If feedback is stuck
Since in app feedback is also spinning, use an alternate path such as a support email or ticketing portal so the issue is logged while you apply the fixes above.

Best Practices

  • Keep one active session per account
Multiple concurrent sessions can cause token confusion. Sign out on unused devices.
  • Clear site data after major updates
After app updates, a quick site data reset prevents schema mismatches.
  • Allow websockets in your network stack
Add exceptions in proxies and filters for wss traffic on port 443 to the Antigravity domain.
  • Maintain an extensions allowlist
Privacy tools are helpful, but add Antigravity to the allowlist to avoid blocked requests. If you want a compact checklist with the exact order to try fixes, bookmark this reference: quick Antigravity loading checklist.

Final Thought

Most cases of One moment, the agent is currently loading are fixed by clearing site data, restarting the Agent Manager, and signing in again. Follow the steps above in order and you should be back to a working agent in minutes.
