Port open locally, not from outside

curl localhost:9200 works on the server but other hosts cannot connect. The firewall is open. What does this ss line explain?

LISTEN 0 4096 127.0.0.1:9200 0.0.0.0:* users:(("java",pid=812))

A.The backlog of 0 means no new connections are acceptedB.Port 9200 is reserved for local users by the kernelC.The java process has not finished starting up yetD.It listens only on loopback, so remote clients cannot reach it
