我使用了很长时间的prestashop Web服务来加载和更新我的产品。 到目前为止一切都还好。 我最近发现 update 操作失败，但 get 操作没有。 我附加了用于更新产品的XML。

响应始终是相同的：

<head><title>524 Origin Time-out</title></head>
<body bgcolor="white">
<center><h1>524 Origin Time-out</h1></center>
<hr><center>cloudflare-nginx</center>
</body>
</html>
这似乎是由于服务器配置所致，我按顺序检查了以下文件：
但是我没有发现任何PUT发生，并且在prestashop日志中没有任何东西
我没有在php_error.log或Apache error.log中出错
我该怎么办？
