Cannot execute job on EE server in Kettle but runs fine using command line

Hi all

We are planning to introduce EE of PDI and are stuck on the problem in title.

Whenever I try to execute a job from kettle using server I get "Unable to Connect to Server. You dont seem to be getting a connection to the server. Check the path you're using and make sure the server is up and running." And this is true to different clients.

But when I try to execute it from command line:
kitchen.bat -rep=PDI_611_EE -user=******** -pass=******* -dir=/home/******* -job=test_job
The jobs runs fine

How does the Kettle read all these parameters - I assume from repositories.xml file?
The repo name is correct, server name is correct.

I suspect it is something trivial...
