429 but rate limits not hit

[echo lotus]

Hello, since an hour now, I got this error: "code":429,"message":"Resource has been exhausted (e.g. check quota).","status":"RESOURCE_EXHAUSTED"

I have a Pro Plan (Level 1) and the limits are far far to be reached.

I tried to create a new project with a new API Key and I plugged it to my Billing account and I also have this issue even if it's a new key.

I am using Gemini 3 Flash Preview (gemini-3-flash-preview)
I need help, my prod is totally broken. It was working good since 2-3 months and suddenly, without any changes, I got this. No more traffic, no more context, nothing...

(EDIT): I noticed it works with Gemini 2.5 flash and Gemini 3.1 flash lite but I want to keep Gemini 3.

Thank you.

Hi there @echo lotus, thanks for posting! I can see from your screenshot that you appear to be using Google AI Studio. Since this server is focused on the Gemini app only, I'd suggest raising this thread in our Google AI for Developers forum!
