Exceptions on Reason: 'timeout' and 'null'

[rts-gordon]

Hi there,
There are some ‘timeout’ errors as follows when I run a Java Spring program with influxdb-client-java. Could someone tell me how to fix these errors? Thanks a lot.

Steps to reproduce:
List the minimal actions needed to reproduce the behavior.

1. setup InfluxDB version 2.7.1 on cloud VM;
2. setup a Java Spring program with Influxdb-client-java version 6.7.0;
3. setup the influx.writeTimeout = 15S;
4. write a lot of data to InfluxDB with this program;
5. run this program for at last a week, there are some 'timeout' and 'null' erros:

Expected behavior:
There are no 'timeout' or 'null' errors.

Actual behavior:
there are some 'timeout' and 'null' erros:
