elastic agent is not sending logs to elastic search

[sandraimmaculate]

hi, i have installed elastic agent in another endpoint using security onion download page added the ip address of elastic agent in firewall host group elastic agent endpoint I'm able to see the the agent healthy in fleet > agent.

But when i search for the agent logs it showing no logs are found.
i opened the ports 8220,9200,443
im able to connect to the security onion using port 8220 using telnet command telnet hostname 8220 from elastic agent endpoint
but not able to connect using telnet hostname 9200 from elastic agent endpoint
is this can be a reason why elastic agent is not sending logs to elastic search
but i allowed the ports.
