使用云防护后,为什么会出现502、快照?

原因可能有以下几点:

  • 1.源站宕机、间歇性卡顿。  请检查源站的存活状态。如何检查源站状态
  • 2.源站响应超时30秒。   超过30秒未响应的请求会被云防护断开,显示502。
  • 3.请核查在云防护DNS设置配置的源站IP是否正确,是否还留存错误的、已经不使用的服务器IP。
  • 4.请检查源站防火墙是否拦截云防护节点IP。   详见FAQ
  • 5.当前页面由于敏感信息已经被网站卫士屏蔽,请删除相关违规信息。
  • -如果域名服务商的防火墙拦截云防护节点IP, 请与域名服务商联系解封并加白IP段。
  • -如果服务器防火墙(安全狗等)拦截云防护节点IP,请将云防护的IP段添加到服务器防火墙白名单中。
  • -如果您服务器未配置任何防火墙,请与您的机房联系,将云防护的IP段添加到机房防火墙白名单中。
