Hey there, no issues to report. If you can provide a x-nf-request-id, we can dig a little deeper.

[Support Guide] Netlify Support asked for the 'x-nf-request-id' header? What is it and how do I find it?

What is the x-nf-request-id header? Web servers and web browser communicate using a protocal HTTP - Hypertext Transfer Protocol. Both web browsers and web servers use something called headers as part of this protocol. The headers that web browsers send are called “request headers” because the browser in making an “HTTP request”. The web servers headers are called “response headers” because web servers send an “HTTP response”. Netlify creates a unique HTTP response header for each request it r…

Hi my ID is

xenodochial-ride-f20e77

I checked console logs on my site, and it seems one of the css files is failing to load
https://senpa.io/web/1.css?979f401357174c363747&979f401357174c363747

Displays a cloudflare error 522

Its strange as

https://senpa.io/web/1.css loads fine but https://senpa.io/web/1.css?979f401357174c363747&979f401357174c363747 errors.

I usually do css?numbersetc for version control, never had an issue before

Ah, seems like you’re proxying to us from CloudFlare. Here’s why you shouldn’t!

[Support Guide] Why not proxy to Netlify?

Netlify runs a CDN backed by several separate network service providers, and our CDN automatically routes your web visitors’ traffic to a network-nearby server to give them the fastest possible response time…as long as you let their browsers talk directly to our CDN! We know you want your your web traffic to be fast; your deploys and rollbacks to be atomic; and your Analytics data to be useful. Additionally, we also want your site to be the most secure it can be - hence our commitment to securi…

Ah ok, Ive never had an issue beforre doing this, was curious as to why it just happened now

I’ve noticed an uptick in reports of this. However, it’s always going to be tricky pinning down an issue when proxying between two providers.

Although I’m looking in to this, our stance is pretty clear: we are unable to effectively support configurations where you are proxying to Netlify from another service.

Ah ok thanks for that, ill remove cloudflare for now then!

I actually use it on all my sites on netlify, but it only affects this one specific site lol

Hey @Mistik,

Turns out that a suite of Cloudflare IPs were banned by us yesterday in response to an incident which could explain the sporadic nature of the impact. This can and will continue to happen; just one of the difficulties when proxying to Netlify from another CDN!

@Pie I’m guessing there’s an interesting story here.

Me too

+1 for not double-proxying CDNs though
