Antigravity and Gemini API suddenly returns “User location is not supported”

Gemini API

Hello,

I’m experiencing a sudden issue with the Antigravity.

Everything was working normally yesterday (September 1, 2026), using the same server, network, and location. Today (September 2), the API suddenly started returning:

HTTP 400
FAILED_PRECONDITION
User location is not supported for the API use.

My public IP is geolocated to Amsterdam, Netherlands, which is a supported region. I also verified that:

  • My public IP has not changed.
  • DNS resolution for generativelanguage.googleapis.com works normally.
  • HTTPS connectivity to Google’s API endpoint is working.
  • IPv6 is not being used.

Since there were no relevant changes on my side, I suspect that my IP or network may have been incorrectly classified or recently reclassified by Google’s location/security system.

Could someone please advise whether this could be a false positive and how I can request a review?

Error details:

Trajectory ID: 528c36a7-c498-4140-8468-2e6c89f209..
Trace ID: 0x3c5727223454c8..

I rely on Gemini API for my work, so I would really appreciate any help resolving this issue.

Thank you.
