Please ask your administrator to check if the DSS server backend is running.

Hi,
Are you running DSS on a server? or locally on your laptop (mac/windows/linux?) ?
Hi, it's on my laptop with Linux 17.10. It was working fine earlier but crash after first tutorial itself.
What is the result of the shell command: DATA_DIR/bin/dss status? DATA_DIR is where you have installed Dataiku DSS on initial installation (https://www.dataiku.com/dss/trynow/linux/)
Hi, the result reads like
backend FATAL Exited too quickly (process log may have details)

ipython RUNNING pid 1958 uptime 0:05:15
nginx RUNNING pid 1959 uptime 0:05:15

Hi,

Something happened to the backend of DSS indeed. Can you send us the log file located in DATA_DIR/run/backend.log please? That will help us diagnose the cause of the backend error.

Can you try to run the commands:

DATA_DIR/bin/dss stop

DATA_DIR/bin/dss start

And see if you can access DSS through your browser again?

Cheers,

Alex

Hi, restarting also does not helped. Since I am just evaluating it, there is hardly anything important to be recovered hence, have removed and reinstall the same and now it is working fine. Don't want to bother you with a 14mb log file debugging. Thanks for all the help and prompt reverts.

Hi,

Restart the DSS server by following commands::

1) go to dss directory in the dss server ( cd dss )

2) ./bin/dss stop

3) ./bin/dss start

now access the DSS UI from the host browser localhost:10000.

If that does not work, Needs to wait for some 5-10 mins and hit the url again( since, the DSS server does take some time to settle down before accepting any connections from the port 10000).
