Hi,
hard to tell what the issue are. It looks like the target prozess is not
properly running or has been killed during the dump (connection reset).
Note that output=tcpserver only works for long running processes. The
process with the attached JaCoCo agent needs to be up and running for
the entire time while executing the dump command.
Another possible reason might be firewall or routing issues.
Regards,
