APM Server transport error (ERR_SOCKET_TIMEOUT): Socket timeout

What should I do to solve the problems below?
I have no idea why the APM Server transport error (ERR_SOCKET_TIMEOUT): Socket timeout"}` error occurs.

`{"log.level":"error","@timestamp":"2024-05-16T05:19:14.619Z","log":{"logger":"elastic-apm-node"},"dt.entity.host":"HOST-40CA2xxxxxxxAA","dt.entity.host_group":"HOST_GROUP-0C777xxxxxxxxA3A","dt.entity.process_group":"PROCESS_GROUP-0AC212xxxxxxxxDB3F8","dt.entity.process_group_instance":"PROCESS_GROUP_INSTANCE-xxxxxxx","dt.host_group.id":"NT","ecs":{"version":"1.6.0"},"message":"APM Server transport error: error fetching APM Server version: timeout (30000ms) fetching APM Server version"}
{"log.level":"error","@timestamp":"2024-05-16T05:19:14.621Z","log":{"logger":"elastic-apm-node"},"dt.entity.host":"HOST-40CxxxxxA0AA","dt.entity.host_group":"HOST_GROUP-0C77xxxxxx3A","dt.entity.process_group":"PROCESS_GROUP-0AC21xxxxxx3F8","dt.entity.process_group_instance":"PROCESS_GROUP_INSTANCE-0A26xxxxxxx39ED16","dt.host_group.id":"T","ecs":{"version":"1.6.0"},"message":"APM Server transport error (ERR_SOCKET_TIMEOUT): Socket timeout"}`

The container comes up and then you get the following error message:
