Gemini API N8N : why am I limited?

Hi everyone,

I’ve been using the Gemini API with n8n for a long time, mostly Gemini 2.5 Pro, and sometimes Flash when there’s an issue. Everything had always worked smoothly.

But since yesterday, I’m unable to make more than one request per workflow. The first call works, but every subsequent one fails, no matter which model I use. I haven’t changed anything in my setup, so this came out of nowhere.

Is anyone else experiencing this?
Any idea what might be causing it or how to fix it?

Hi @Ovise ,

Thank you for reaching out.
Could you please let us know which error message you are getting?
