我建立了一个脚本来从Gmail API（我以前的1000封电子邮件）获取数据，我将这个脚本上传到我的网站到一个不同的文件夹只是为了测试，该脚本第一次正常工作，巨大的数据开始加载在页面上，但如果我尝试重新加载页面，它会给出错误504 Gateway Time-out The server didn't respond in time.事实上，我的整个网站停止工作无论我的网站打开我的网站，我得到同样的错误，但如果我关闭浏览器并重新打开它或等待5分钟，然后一切再次开始正常工作。但如果我再次运行脚本，同样的事情再次发生。这是脚本BTW我的网站给出了504错误当我运行特定的脚本

任何猜测可能是错的？
