[resolved] Talend Studio Remote Server Connecting to Socket Refused

[Anonymous]

I have a Talend Administrator Center and Job server running in AWS (same instance)
When i run the job using Talend Platform for Data Management 5.5.1 on remote server (AWS Job server).
It returns " connection refused" but the job runs successfully on Job server. The problem is I can not see the messages which should return from server.
But when I forward the ports (3334 to 4445) to my computer's private ip on my router, it works 100% fine.
Any suggestions would be greatly appreciated.
Error Message:

The problem with the statistics is it always use different IP ports. You can configure the IP port range in the studio but it remains a range. I suggest you take care for a transparent network between TAC and job server.
To be honest the decision for a none stable IP port for the statistics is not easy to understand for me. 
In the TAC you can - and should - switch off the statistics for the task in the task settings. In the studio you can switch off the statistics in the Run view under advanced settings.

thanks jlolling
I disable the statistics setting in Talend studio and now it works fine.

Hello,
We have a similar problem with the production talent jobs which try to run the statistics but fail to connect to the random port.
In the Talend Open Studio for Data Integration, when I uncheck the 'Statistics' box, the do not run.
How can I disable this feature in the production (built jobs) as well ?
Thank you.

Hello, 
I am having a similar issue with Talend 6 Big Data Platform, if I run the job from the studio in a remote job server it works fine but not showing statistics,  if I do debug run it fails with the error below. 
the problem is that if I run the job from the TAC it keeps waiting for the execution and never executes. 
The ports are open in the IPTABLES (Ubuntu server), but the job server doesn't seem to be using them. 
Any recomendations?

I had similar issues and found a solution:

in

${REMOTE_ENGINE_INSTALL_DIR}/etc/org.talend.remote.jobserver.server.cfg

# Enable the process message publisher or not. false by default
org.talend.remote.jobserver.server.TalendJobServer.ENABLED_PROCESS_MESSAGE=true

Restarted the remote engine and I no longer had the [Stastistics] Connection Refused error
