We had the instance created for us by a third party. I do not know what rules there are in the outer system. When you say "open right up" if you mean to disable the firewall, i tried it. If there is some other point i need to look into for extra security rules, could you propose where?
The machine name is like: machineName.awsxxx.cloud.companyName.com
I had a short talk with the party, and they were telling we need to register a domain name and then reroute it to Qlik Sense hub. Is there a necessity for all these complications? We will use it within the domain companyName.com.
