Recovery Checkpoint Not connecting to Target Server

[devanpeebles]

Basically I have a simple job with a check point set up in it that I've deployed and have configured a job in the TAC to run.  When the job fails and triggers that check point I can see it in the recovery console but when I try to actually recover from the check point I get an error "Connection to server failed"

I can see on the job server in the TalendJobServersFiles\jobexecutions\logs a folder has been created for the job execution of the recory.  And in the logs on the job server i see this,

Any idea what the problem is?  The job runs perfectly fine if I run it without trying to run it from the recovery point.

I think we need your job or more details to investigate the issue, can you please open a ticket to our support portal?

Right now I'm just pocing check points so the job is super simple.  Basically just writing something out to console, reading a file and logging it.  To create the error I'm just renaming the file.  Here's a screen shot of the recovery console, I ran the job once with the file available that's the first run which finishes successfully, then I renamed the file ran it again which errors out, then I tried to recover from the check point and that's when I get the Connection to server failed error when trying to recover from the check point.  So i'm just wondering if there's something obvious wrong with it.

Even i am facing the same issue on talend 7.2.1 studio and i could see the below error in the technical logs,

org.talend.administrator.scheduler.exception.ExecutionTaskException: Execution server not found.

How do we need to fix this or is this a bug in talend 7.2.1?
