Zabbix Server’s auto-discovery cannot detect the host.

My zabbix_server can ping my agent and access port 10050. My zbbix_agent can also ping the server and access port 10051. But the agent log shows access denied, and the auto-discovery I set on the web page cannot detect the corresponding agent. How can I locate the problem?”
