It was kind of popular problem showing 'Disconnect' status in Zeppelin 0.5.0, while it was using separate websocket port and in may cases, that separate websocket port was blocked by firewall or proxy.
However, from 0.5.5, websocket is no longer uses separate port. So, seeing 'disconnect' while webapp is normally loaded is very uncommon. If you still see 'disconnect', could you open such things like 'Developer tools' or 'Javascript console', and go to 'network' tab and find 'ws' (websocket) connection? That information might help to narrow down the cause of the problem. Thanks, moon On Wed, Nov 25, 2015 at 7:17 PM Hyung Sung Shim <hss...@nflabs.com> wrote: > VM zeppelin works?
