Urgent: AI Studio suddenly stopped working — “Failed to list models: permission denied”

Hi everyone,

I urgently need help with a sudden Google AI Studio issue.

It was working normally with the same Google account until today, but it suddenly stopped working and now shows:

Failed to list models: permission denied. Please try again.

It also says that it cannot verify the subscription status of my Google AI account.

What makes this particularly confusing is:

  • The Google Cloud Console still opens normally.
  • My Google account itself can log in normally.
  • AI Studio was working normally with the same setup before this happened.
  • The Google Cloud Console usage page works OK and shows that my recent usage had already decreased over the past few days, and now AI Studio has completely stopped working.

I am quite concerned because I need AI Studio urgently for ongoing work.

Has anyone experienced the same issue recently? Is this likely to be an AI Studio service-side issue, region/IP detection problem, or an account entitlement problem?

Any information about a known outage, workaround, or confirmed fix would be greatly appreciated.

Thanks.
