芹菜花与apache2反向代理ssl握手失败websocket

我正在尝试为apache2后面的花设置反向代理，如本文Celery Flower Security in Production中所述 .

来自花的Https页面加载工作正常通过代理，但它打开以更新仪表板的websocket没有 - ssl握手失败并且没有返回响应 . 我在ubuntu 12.04上使用apache2 2.2.22并且我通过常用的补丁添加了mod_proxy_wstunnel以便隧道连接websocket . 我在127.0.0.1:5555通过supervisord运行花 .

这是我的apache .conf的相关部分

SSLProxyEngine On
SSLProxyVerify none

ProxyRequests Off
ProxyPass /update-dashboard wss://127.0.0.1:5555/update-dashboard
ProxyPassReverse /update-dashboard wss://127.0.0.1:5555/update-dashboard

ProxyPass / http://127.0.0.1:5555/
ProxyPassReverse / http://127.0.0.1:5555/
<Proxy  *>
Order deny,allow
Allow from all
</Proxy>

这是最终超时后的请求

"GET /update-dashboard HTTP/1.1"
 500 419 "-" "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML,     like Gecko) Chrome/43.0.2357.124 Safari/537.36"

这是apache2错误日志的输出

什么想法可能会出错？我尝试了很多不同的apache2设置无济于事 . 谢谢阅读！
