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.
Qlik Sense is accessing fine on my few clients but for a specific client it is not working when I asked to switch it some another internet access it is working fine. So I am sure its something relate to security. My question is do Client who is outside of your network need to open these ports in his machine or network too to access Qlik Sense ?
