External URLs cause 429

Is anyone getting success when using external uris (aws bucket links, s3 etc)

This would be for Gemini api, generate content requests in AI Studio

I get 429 rate limit and resource exhausted errors even though I’m at maybe 1% of limits. But upon using files API and uploading it all works fine.

It seemed to break within the last 2 days.

Same issue here. The 2.5 models (pro and flash) both work, but any 3.x model gives me a 429 error any time I include an external url.

Same here, works on
https://generativelanguage.googleapis.com/v1beta/models/gemini-2.5-flash:generateContent
but not on
https://generativelanguage.googleapis.com/v1beta/models/gemini-3.5-flash:generateContent
My request body has an image mime type with a public httpx fileUri

It only works via Google Agent Platform.
use enterprise=True with service account key or ADC (Application Default Credentials) for authentication on genai sdk

Sorry about this Stephen - this is now fixed.
