Error on sudo systemctl enable --now elasticsearch

Elastic Stack Elasticsearch
1

Hi, I am new here.
I am trying to install elasticsearch on my Centos 7.8 to support Magento 2.4]
I followed all instruction but on enabling it with command

sudo systemctl enable --now elasticsearch

I have this error

Job for elasticsearch.service failed because the control process exited with error code. See "systemctl status elasticsearch.service" and "journalctl -xe" for details.

Then searching on journalctl -xe

Firewall: TCP_IN Blocked IN=enp2s0f0 OUT= MAC=ac:1f:6b:81:37:10:60:9c:9f:bd:2c:90:08:00 SRC=79.124.62.34 DST=134.119.190.175 LEN=40 TOS=0x00 PREC=0x00 TTL=246 ID=54398 PROTO=TCP S

Which ports do I have to open on Firewall if this is the problem? Opening port I have this other error:

ott 15 14:06:41  systemd[1]: Unit elasticsearch.service entered failed state.
ott 15 14:06:41  systemd[1]: elasticsearch.service failed.

ott 15 14:06:41  sudo[5704]: pam_unix(sudo:session): session closed for user root

Do you have any idea of how to proceed?
Thanks

I don't know if it's the problem but at least if your node needs to communicate with other nodes, open 9300.
Or with another machine where the application is running, open 9200.

Could you share the full elasticsearch logs?

This is not elasticsearch logs. Could you go to the elasticsearch logs dir and share the logs please?
