Gemini API blocks Tokyo Linode IP as unsupported location

Gemini API

Hello,

Gemini Developer API requests from my production server are rejected with:

{

"code": 400,

"message": "User location is not supported for the API use.",

"status": "FAILED_PRECONDITION"

}

Server public IP: 139.162.122.175

Provider: Akamai Connected Cloud / Linode

Server location: Tokyo, Japan

ASN: AS63949

The server-side request was made to:

https://generativelanguage.googleapis.com/v1beta/models

Public IP geolocation identifies this IP as Tokyo, Japan. Japan is listed as a supported Gemini API region.

Could you please review whether this IP range is incorrectly classified or blocked for Gemini Developer API access?

I can provide the exact UTC timestamps and sanitized API response if needed.

Update:
I reproduced this with the exact same Gemini API key.

  • From my local Mac network in Taiwan: HTTP 200 from /v1beta/models

  • From the Linode instance at 139.162.122.175 in Tokyo: HTTP 400 FAILED_PRECONDITION, “User location is not supported for the API use.”

The API key, project, endpoint, and request are identical. The only variable is the source network/IP.
