Connection to the Qlik Sense engine failed for unspecified reasons.
Qlik Sense 3.1 server issues this message on login to hub: "An error occurred Connection to the Qlik Sense engine failed for unspecified reasons. Refresh your browser or contact your system administrator."
Any assistance or ideas would be appreciated. I'm relatively new to Qlik; this is the first time we've tried to install 3.1.
I found a possible solution. In QMC/Virtual Proxy/Central Proxy(Default)/Advanced/Host White list I setup the ip address of our server (the server name may be also suitable). After that, the problem is disappeared.
