I spent an inordinate amount of time trying to figure out why my Oracle ODBC connection that worked in QlikView and in Qlik Sense desktop would not work in Qlik Sense Enterprise. I stumbled on a community article that suggested unchecking the Standard Mode checkbox in Engines -> Central -> Edit -> Advanced. In essence putting Qlik Sense in Legacy mode. To my amazement that fixed it. However I am concerned about running Qlik Sense in Legacy mode.
Anyone else out there have this issue and a better answer than running in Legacy mode?
