elasticsearch - Can't curl the response at port 9200，but can ping directly

Question

I have deployed elasticsearch in my remote server at port 9200, and I ran the command:

curl http://localhost:9200

it returns the correct response.

But when I use this command locally:

curl http://xxx.xxx.xxx.xx:9200 (xxx.xxx.xxx.xx is remote server IP), it shows connection failed.

but when I am using the command: ping xxx.xxx.xxx.xx -p 9200,it connects successfully

remote: curl http://localhost:9200 (ok)

local: curl http://xxx.xxx.xxx.xx:9200(failed) ping xxx.xxx.xxx.xx -p 9200 (ok)

确保设置network.host设置为非环回地址。放network.host: 0.0.0.0
