Hi...I am getting below error while trying to connect to DSS. It was working fine earlier.

Could not connect to DSS server

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

Unknown error
HTTP code: 502, type: Gateway error

Kindly check and help!

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

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?


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.

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).
