Failed to list imported projects: permission denied — persists after enabling Generative Language API

Google AI Studio
1

Hello,

I’m experiencing a persistent access restriction on Google AI Studio / Gemini API.

When I open AI Studio or try to generate/use an API key, I get:

  • “Failed to list imported projects: permission denied. Please try again.”
  • The original error before that was a 403 PERMISSION_DENIED when calling the Gemini API with my key.

What I’ve already tried:

  • Enabled the Generative Language API in my Google Cloud project (confirmed as “Enabled” in APIs & Services)
  • Confirmed I’m the Owner of the project
  • Tried in an incognito window / cleared cookies
  • Confirmed my country is listed as a supported region for the Gemini API

The error persists even after these steps, which suggests it might be an account-level restriction rather than a project configuration issue.

Account details:

  • Country: [seu país]
  • Approx. account age: [há quanto tempo você tem a conta Google]
  • Browser: [seu navegador]

Could someone from the team take a look at this? I’d appreciate any guidance on what else might be causing this.

Thank you!

Hello @Breno ,
We have recently rolled out a mandatory age verification initiative across signed-in customers globally, Accounts that have not completed explicit date-of-birth/identity verification should do so by navigating to Google Account Age Verification or verifying date of birth in Google Account Personal Info."

Also, Make sure you are accessing AI Studio from one of the supported regions, disconnect any VPN, proxy, or iCloud Private Relay and access AI Studio directly.

After completing these steps, please try again in a few hours, If you still face issues, please let us know.
