Can't connect to pigpio at localhost(8888) Can't create callback thread. Perhaps too many simultaneous pigpio connections

[Madhuraank]

Have connected DHT11 to Rpi4.

VCC--pin 1

datapin--gpio4

Ground pin--pin 6

It works fine fine but after giving the result for few times then I get this error. New to pigpio please do help me figure out what's wrong

import time
from pigpio_dht import DHT11, DHT22
while True:
        gpio = 4 # BCM Numbering

        sensor = DHT11(gpio)
#sensor = DHT22(gpio)

        result = sensor.read()

        temperature=([value for value in result.values()][0])
        print(temperature)

        humidity=([value for value in result.values()][2])
        print(humidity)
        time.sleep(10)

Output:

28
46

28
46

28
46

28

and then I get the following:
