Could not connect to SUM

Hi All,

I am trying to Update from SP3 to SP5

When I try to open Lifecycle management on HANA Studio it gives this erros

Error: Could not connect to the Update server

Possible reason: Network error occurred or Update server is not running

And I went in to HANA box and browsed to /usr/sap/<SID>/SUM

and then started ./sum.sh

this triggers a command line ...

What am I missing here .
