AI Studio access suddenly denied (Failed to list models / redirected to available regions)

Hi, since today (19 Jan 2026) my Google AI Studio access stopped working.

Timeline:

  • Worked until ~11:00
  • Started failing around ~13:00

Error:

  • “Failed to list models: permission denied”
  • Then redirected to the “Available regions” page (Eligibility / age screen)

Details:

  • I’m in Germany (supported region)
  • Age is 18+ (DOB 1999)
  • Tried with and without VPN: same result
  • Happens in all browsers
  • Another Google account works on the same device/network
  • This account is a Workspace account and I’m not an admin

Can someone check whether my account is flagged or if there’s a backend eligibility issue?
