Error deploying REST service onto ESB Runtime Server linux

[nmodi]

we have developed REST service that works fine on local machine using 

http://127.0.0.1:8090/restservice/test endpoint 

and we were even able to deploy this onto nexus using TAC publish job however I keep getting an error while trying to 'Deploy' REST service onto runtime server,

Hi nmodi
Which version of ESB product are you using? We will try to reproduce the issue and check if it was a bug or it is a configuration issue. If possible, please share your job.

We are on 6.4.1 enterprise version & this is the first time we are deploying something to ESB. Job works fine locally & I have followed everything as mentioned in this document.

@shong any response on this? I cant really post the screenshot since it is internal but any idea on why I am getting this error? why it is trying to look for nexus on localhost even though we have updated nexus server name appropriately on TAC.

Job server publish & deployment worked absolutely fine, why runtime server is having issue while deploying the job?
