Host with intermittent connection to zabbix server

Hello,
In an instance of Zabbix Server we have a host which has a Zabbix Agent installed for monitoring, however this has moments when we lose the connection to the computer from the Zabbix Server, however when reviewing the logs, the drop is only a couple of seconds. How should we proceed to further review the equipment, since they have been ruled out problems that have to do with the network configuration.

Thank you very much for your help,
Regards
