Occasionally missing visitor logs

The version of matomo is 4.2.1, running on kubernetes, mysql is 1 master and 2 slaves, and the matomo container is enabled for scaling 2.
The current phenomenon is that all the visitor behavior logs will be lost at irregular times, but the visitor’s request log can be found when querying the nginx log.
The following is an excerpt from the nginx log, the visitor ID is: cfadba50d6c51b3a.

But through “Visitor Analysis -> Access Log” to query the log based on the visitor ID, nothing is returned.
The request status in the nginx log is 204.
