why cannot send list of active checks to "xxxx": host xxxx not found,and i must restart zabbix_server then can found it。

zabbix server didn't auto found the agent ,you must restart the server，then it can found





I add the new web monitor ,also restart the zabbix_server,then it can found.

zabbix server version is 6.4.9
zabbix agent version is 6.4.9
