Hi
I need to send some packet in JSON over postman to logstash on Mac
Logstash was already established on localhost:5001- UDP

[2023-10-19T19:19:07,238][INFO ][logstash.agent           ] Pipelines running {:count=>1, :running_pipelines=>[:pi_customer], :non_running_pipelines=>[]}
[2023-10-19T19:19:07,255][INFO ][logstash.inputs.udp      ][pi_customer][c4dcf849d002517842a72f988bc9a7c0471cd08de6075f97c8aa1defe66ca5b8] UDP listener started {:address=>"0.0.0.0:5001", :receive_buffer_bytes=>"786896", :queue_size=>"2000"}

but I I want send “whatever” I got

Error: connect ECONNREFUSED 127.0.0.1:5001

What’s wrong?
Thx for tips

You appear to be using 0.0.0.0 instead of 127.0.0.1 (local host).

Try that first.
