Why is it that Antigravity is now always regularly coming to this unexpectedly after doing updates.

Hi @Elius,

Thank you for sharing the screenshot.

Please try the following steps:

  1. Confirm You Are on the Latest Release (v2.24.0): Ensure your Antigravity App is updated to v2.24.0 (Changelog), which includes authentication recovery improvements and a fix for model lists failing to populate after signing out and back in.
  2. Re-authorize Antigravity in Your Firewall/Antivirus & Test the Endpoint: Because an application update replaces the binary on disk, local firewall or security software rules tied to the previous binary hash can silently drop connections. Refresh Antigravity’s permission in your firewall/security software and verify that your machine can reach the service from a terminal:
    • curl -sv https://daily-cloudcode-pa.googleapis.com -o /dev/null
  3. Disable Post-Quantum TLS (tlsmlkem) as a Test: Some routers, firewalls, and deep-packet inspection (DPI) filters drop larger Go Post-Quantum TLS packets (EOF). Try launching Antigravity with the environment variable GODEBUG=tlsmlkem=0:
    • macOS / Linux: export GODEBUG=tlsmlkem=0 (then launch Antigravity from the same terminal)
    • Windows (PowerShell): $env:GODEBUG="tlsmlkem=0" (then launch Antigravity from the same PowerShell window)
  4. Check VPN / Proxy Settings: Temporarily disable any active VPN, proxy, or custom DNS filter (or test on a mobile hotspot) and click Sign in again.

Please let us know your OS version and the output of the curl test above if the issue continues.
