Not quite untangling this yet. Since it is working for you on Linux, I tried that now.
I first start DHIS Live with the default URL: Then I start the H2 console. The following URL does not work, as expected: jdbc:h2:../../dhis-live/database/dhis3 But this one does: jdbc:h2:../../dhis-live/database/dhis3;AUTO_SERVER=TRUE However, this one does not work (with or without ;AUTO_SERVER=TRUE) jdbc:h2:tcp://localhost/~/Desktop/dhis-live/database/dhis3 Curiously, after the ~ gets substituted with /home/knutst/, the H2 console does not seem to find anything, and connects me with an empty database: jdbc:h2:tcp://localhost/home/knutst/Desktop/dhis-live/database/dhis3 This is increasingly baffling...
