I am having issues to connect to SQL Server via Qlik Sense. I read threads from other users who experienced similar issue, but was not able to establish connection. What bothers me is that I was able to test connection as referenced in https://blogs.msdn.microsoft.com/farukcelik/2007/12/31/basics-first-udl-test/ and had no problems, but Qlik refuses to establish the same connection with identical credentials. I even installed SQL Server Native Client 11 on Qlik Server (as suggested by others) - now it shows up in the list of connectors, but it didn't help.
Thanks for your input.
I deleted my original reply to this thread by accident, but I was able to fix the issue by switching QS Services from QSAdmin to UserName
I found a similar thread with the same issue that helped me.
