"The service is receiving too many requests from you" OpenAI node (Tier 5 user, nowhere near actual limits)

[Daniel_Kempe]

Hi all,

Been using a flow for quite some time now with no issues, but all of a sudden, getting various problems.

The one that makes no sense is an openai node (using image gen 1) to generate images with openai, HOWEVER, i’m receiving the “The service is receiving too many requests from you” error message.

I am not seeing this issue anywhere else, other apps etc that are all using the same api key. I’m on tier 5, and I know for sure, I’m nowhere near the official limits. This seems to be linked with n8n specifically, is that the case? How do we fix?

n8n version: 1.107.3 (Latest Stable)

n8n cloud

Most of the error is shown below (can’t add more than 5 links for some reason):

Also, to add to this, in the n8n flow, I have another openai request that’s working just fine, so this would lead me to believe that n8n themselves are being rate limited. HELP!

Logically I would say it is about your workflow retrying many times which makes the requests stack up. But I guess this isn’t about OpenAI or your workflow because you said it worked fine before. And the error states it’s from Cloudflare. So your request is being rejected before it reaches the service.

• Are you self-hosting and is your IP reputation is robust?

• The error message mentions the cookies. Perhaps Cloudflare flagged you as a bot for this and banned you.

Here is my conspiracy: I’ve seen too many people literally abuse OpenAI to make automative social media posts. And not just any abuse, literally torture at this point. So Cloudflare probably updated their rate-limiting policies and made it tighter. I’m not sure about it though I’ve never used OpenAI before.
