AI Assistant isn't working. What should I do?

When I try to use the AI Assistant inmediately I receive the following message: “Error: Something went wrong before I could finish that response. Please try again. Something went wrong before I could finish that response. Please try again.”

What can I do? Is it a problem of N8N or is it a problem of my account?

Hey @Carlos_Esteban_Arcin, quick things to check:

Try a different browser or incognito mode

the AI Assistant is a cloud feature tied to your subscription. If you recently changed plans or your trial expired, it may have been disabled.

Let me know if it helps

Did you run out of credit?

Hi @Carlos_Esteban_Arcin Welcome!
On Cloud, that string is what the assistant returns when the AI credits behind it are exhausted. The message just doesn’t say so yet:

The request that actually fails is GET /rest/instance-ai/credits, so open the browser network tab, send one message to the assistant, and look at that call rather than the chat call. It returning 500 while chat, threads and preferences return 200 is the credit check dying, and it points at the account, not the editor.
Cloud AI credits are separate from the workflow builder credits, and the Cloud assistant can’t run on your own LLM key yet, so once they’re spent the assistant stays down until the account has more.
