Hello,

Recently our system administrator added CloudFlare on QlikSense Servers for security purpose.

We have modified key="WebSocketPingInterval" value="10" in proxy.config , so we won't get the connetion lost in hub,  but the error is still occuring in data load editor. Sometimes it appears right after data load editor is open ,or the error appears after 2-3 minutes.

We also add the public adress in "Host To Allow" List from Virtual Proxy.

 It's a known problem with Cloudflare regarding connection lost in data load editor?
