I have recently experienced very strange behavior while using Tableau Desktop. Tableau Desktop is installed on a server (Windows) and was used to create several .twbx files (all extracts). I can open each file separately (open first one, close it, open second one, close it, etc.). Problem arises when I try to open/use 2 files at the same time. First one is opened normally, but the second one is trying to connect to the database, although it is set up to use extract. What’s even worse, it fails to connect, although I can connect to the database when I’m using just one .twbx file.
This problem doesn’t occur when I open files in Tableau Desktop locally (on my personal PC).
