How to configure elasticsearch (in a PC) to receive connections from a devboard?

This question is related to this other one:

I installed a elasticsearch python client in Google Coral devboard (

I want to establish the communication between the devboard and a Windows Laptop. In the Windows laptop, I have installed Elasticsearch 6.x.y.

I have put the firewall down and created a rule to allow traffic to port 9200. But still cannot connect.

I have tested with:

nc -vz 9200


curl -XGET ""

I am not sure if this is related to the "publish address"

I have read this: How to configure the publish address of elasticsearch 5.0 with CLI flags

Any suggestions?
