使用apache http服务器升级到WSO2时出现SSL错误为5.1

我们正在将WSO2 IS 5.0 SP1升级到WSO2 5.1。与WSO2的通信是通过ApacheHTTP服务器2.2进行的。这种通信在WSO2 IS 5.0 SP1中运行良好。但当我们升级到5.1时，浏览器上会显示以下错误消息

Proxy Error

The proxy server could not handle the request GET /services/EntitlementService.
Reason: Error during SSL Handshake with remote server

在检查apache日志时，我们得到以下错误
