Hi everybody, yesterday I have used DHIS2 without any problem, but since morning I had an issue. when I launch the DHIS2 I get an error as “HTTP ERROR: 503 Problem accessing /. Reason:SERVICE\_UNAVAILABLE”. But when I change another Data Base the dhis2 is launched successfully. could someone tell me what the issue and how to solve it? Because The data base I was using yesterday contains many data. so please help me on this issue. Note that I’m using dhis2 in local mode Best regards. Franck ---

Please remember to always specify your setup (even if you have done so in another thread earlier): 503 usually indicates a problem with your db. Is this DHIS2 Live with the H2 database? Or with Postgres? Any messages in your log? Try staring it from the DOS command line like this: java -jar dhis2-live.jar That should give you more messages than in the Live log > **···** > > On Fri, Feb 21, 2014 at 2:34 PM, HAKIZIMANA Franck [francescohaki@gmail.com](mailto:francescohaki@gmail.com) wrote: > > > Hi everybody, > > > > yesterday I have used DHIS2 without any problem, but since morning I had an issue. when I launch the DHIS2 I get an error as "HTTP ERROR: 503 > > > > Problem accessing /.

Something seems to be wrong with your periods, you are using six month periods? > **···** > > On Fri, Feb 21, 2014 at 3:23 PM, HAKIZIMANA Franck [francescohaki@gmail.com](mailto:francescohaki@gmail.com) wrote: > > > I’m using dhis2 2.14 Live with Postgres as Data Base.
