Custom page, Status code 500

Hello, I am trying to insert custom pages. But I got this message in the preview:
Custom error preview failed
Status code 500 received while retrieving model from …
target: one of the
cf error: 1000s
block: ip-ban
block: flow limit
block: client-auth
block: basic-sec-captcha
block: country-captcha
block: adv-sec-captcha
block: waf
block: iuam-basic
cf error: 500s
always online: no copy
phishing: warn
regulation: block

I tried with several errors (IP / Country Block, 1000 Class Errors) and their associated tokens.

Other verified prerequisites:
-max 1.5MB size, but no image
-W3 validator OK
-Page status 200 OK

This page is hosted on gitub (unlike other CloudFlare related production sites), could this be the cause?

Basic HTML : link

  <!doctype html>
    <html lang="fr">
    		<title>Erreur !</title>
    		<meta charset="utf-8">
		<link href="style.css" rel="stylesheet" type="text/css">
		<div class="contentWrap">

Can you try and make your external file to style.css into HTML using <style type="text/css"></style>?

Also make sure to minify it due to possible character limits, if so.

I assume yes.

Have you checked this source:


The problem was the external .css file.
The error seems so obvious to me now.
Thank you @fritexvz :+1:
