Failed to connect to network connection

[StRuoff]

I want to do the following:
I have an RCE instance running on Machine A (Linux), where some components are published. I want to run a workflow that executes one of the components, but need to call it via console (inside a script that I have), so what I call is (for testing if everythin is set up corectly):

rce.exe -p default --headless --exec "components list -r ; stop"
or
rce.exe -p default --batch "components list -r

and get the following Message:

Failed to connect to "129.247.149.169:21000": Ignoring a request to connect to 129.247.149.169:21000 (activemq-tcp) as the network layer is shutting down (Connection details: activemq-tcp:129.247.149.169:21000(connectOnStartup=true, autoRetryDelayMultiplier=1.5, autoRetryInitialDelay=5, autoRetryMaximumDelay=300, autoRetry=true))

If I open the console with rce.exe --headless -console and type the commands rce components list -r, everything runs as expected.

Starting a local RCE instance in advance and then connecting to it via "ssh wfadmin@localhost" could be an option, but would make it one more "manual" step, which we do not want to have in our approach.

I attached the corresponding log file:
debug.log

Some additional Info:
If I run a workflow (Input, 2 custom components (both remote), Output),via
rce -p default --batch "wf run -p placeholder_file workflow_file"
it works just fine.

We do it similarly in our automatic RCE test and deployment service via "{rce}" --profile "{profile}" --batch "wf run --delete never -p {phvf} {workflow}" -data "{workspace}"
