Hi everyone, I am a bit beginner
I’m getting a persistent HTTP 400 (FAILED_PRECONDITION) error when using
Gemini models in Antigravity. Claude models work fine on the same setup.
Error details:
{
“error”: {
“code”: 400,
“message”: “User location is not supported for the API use.”,
“status”: “FAILED_PRECONDITION”
}
}
Environment:
- Antigravity IDE (latest version), reinstalled with global storage cleared
- Working from Indonesia, cloud/VM infrastructure also based in Indonesia
- Previously used a VPN for other work, but this issue persists even
after fully disabling VPN and reinstalling the app - Only Gemini models are affected — Claude works normally
What I’ve tried:
- Reinstalled Antigravity completely
- Cleared global storage / app cache
- Disabled VPN entirely
- Verified my actual IP/location resolves correctly to Indonesia
None of the above resolved the issue. Based on similar threads here,
this looks like it might be related to account/project provisioning
on the backend rather than actual geolocation, or possibly an IPv6
routing issue (I saw another user fix a similar case by blocking IPv6
traffic to Google’s ranges). I’d rather not touch shared network
infrastructure without confirming the root cause first.

Has anyone from the Antigravity team looked into this? Would appreciate
any guidance on whether this needs to be fixed on Google’s side.
Thanks!
