Getting a Forbidden Error for Requests via Cloudflare

API Spot/Margin API
1

Here’s the error message I’m receiving:

{
  "error_message": "Access to the requested resource is forbidden.",
  "error_stack": "ForbiddenError: Access to the requested resource is forbidden.\n    at httpRequestFunction (index-cf.js:5062:21)\n    at async Object.fetch (index-cf.js:7896:24)",
  "error_name": "ForbiddenError"
}

I’ve created a minimal reproduction repository here: GitHub - chesha1/bn-getFlexibleProductPosition-reproduce

My application runs fine locally, but I encounter this ForbiddenError after deploying it to Cloudflare.

I have already confirmed that the IP restrictions for this API key are disabled (set to “No restriction”), as shown below:

I’m wondering if Binance might be blocking requests originating from Cloudflare’s IP ranges. Is this expected behavior or a known issue?
