What is the name of the domain?

What is the error message?

413 Payload Too Large on an HTTP upload to a non-proxied endpoint

What is the issue you’re encountering

413 Payload Too Large when uploading a 250MB file

What steps have you taken to resolve the issue?

I un-proxied the particular endpoints that are being referenced.

What are the steps to reproduce the issue?

Proxy the endpoint, see the failure, un-proxy the endpoint and continue to see the failure

If the hostname is proxied, then you may be hitting Cloudflare CDN’s max request body size of 100MB for Free & Pro plans or 200MB for Business.

But if it’s a DNS Only :grey: hostname, I don’t see how Cloudflare could be impacting this. The error message must be coming from elsewhere in your setup.

So in my case then it apparently was a DNS caching issue (either browser or TTL). So even though I had un-proxied the hostnames via the cloudflare console, my client/browser was still resolving the CNAME to a cloudflare endpoint. In hind-sight that makes sense.
