Influxdb does not close TCP connections - tcp

Question

I connecting to my influxdb (1.1.1.1:8086) from my pc (2.2.2.2) to perform some queries. I find out, my server keeping the connections opened:
netstat -tpn | grep 8086

When I tried it on my localhost, the connections decreased when I stop sending queries or data to save almost immediately. There is also no query performed by influxdb:
InfluxDB shell version: 1.6.0
> SHOW QUERIES
qid query database duration status
--- ----- -------- -------- ------
670 SHOW QUERIES 537µs running
How can I close this session in linux? How shoul I configure influxdb to close this sessions automatically(on local host I have default configuration).
Versions:
Python lib influxdb (5.1.0)
OS Ubuntu 16.04.5 LTS
PROGRAM:
from influxdb import InfluxDBClient
import random
host = '1.1.1.1'
port = 8086
user = 'user'
password = 'password'
dbname = 'database'
client = InfluxDBClient(host, port, user, password, dbname)
json_body = [{"measurement": "TEST",
"tags": {"Location": "local0"},
"fields": {"Value": random.random()}}]
print(json_body)
client.write_points(json_body)
