I am making a program for Android that shows a demonstration of the PC screen on the phone. On Windows the code works fine, but when I build the apk via Bulldozer and try to connect via IP to the server where the image is taken, an error appears in the console (via adb logcat). Application code:

from kivymd.app import MDApp
from kivy.lang import Builder
from kivy.uix.image import Image
from kivy.clock import Clock
from kivy.graphics.texture import Texture
import cv2
import numpy as np
import logging

logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)

If I go to the site from where the screen sharing is taken from my phone, everything works fine there.
