This issue seems to be related to how the CDN server handles the HTTP
Referer header.
Paolo: Is there a GNOME GitLab project where we can raise an issue to
ask the CDN admins to help?
The 403 response occurs when I include the referrer:
$ curl 'https://download.qemu.org/' -H 'Referer: https://www.qemu.org/' -o -
<!DOCTYPE html>
<head>
<base href="//error.c.cdn77.org/" target="_blank">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta name="author" content="(c) 2019 CDN77">
<meta name="description" content="">
<meta name="keywords" content="">
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="robots" content="nofollow" />
<link rel="stylesheet" href="css/main.css">
<link rel="shortcut icon" href="img/favicon.ico" />
<title>Forbidden</title>
</head>
<body>
<header class="Header">
<div class="Header-wrap">
<span class="Header-errorNumber">Error 403</span>
<h1 class="Header-title">Forbidden</h1>
<div class="Header-description">Sorry, you don't have
permission to access this resource.</div>
</div>
</header>
</body>
Now without the referrer:
$ curl 'https://download.qemu.org/' -o -
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title></title>
</head>
<body>
<h1>Index of /</h1>
<hr>
<table id="list">
<thead><tr>
<th style="text-align: left; width:55%">Filename

<th style="text-align: left; width:20%">File Size

<th style="text-align: left; width:25%">Date</th>
