When running Flask scripts in localhost, I tried to access the webpages from another device in the same local network.
Although I'm able to view the webpages, I frequently noticed this error popping all of a sudden with random numbers near my IP in my console causing OSError and denying access for my later requests to the Flask server.

For all I know, I know nothing about sockets or other things thats in my error.
How do i stop such errors from happenning after all I'm just rendering a HTML template as a response?
Edit :
I'm adding a part of my Flask script here from which I still get the error. And again the error is something that occurs when I try to access my webpages from other devices connected in the network
from flask import *
app = Flask(__name__)
#app.route('/')
def index():
return render_template("home.html")
#app.route('/download')
def downloads():
return render_template("downloads.html")
if __name__ == '__main__':
app.run(host="0.0.0.0", port=5000 , debug = True)
This time also I got similar error as follows

Does anyone know what I should do? I receive this error everytime I interact with my localhost.
It does not crash, my terminal just blows up with these exceptions. Does anyone know how I should proceed with this issue?
I know this is alot of errors but I am starting to learn more about Django so your help would be greatly appreciated. Thank you!

The issue is raised by the fav.ico because django server is always resetting after not finding a favicon so If you add one. Even though If you never explicitly load one, django try and load a default one from the root of the project. you can use favicon io to make a simple fav icon. you put it inside your static folder and load it like that :
{% load static %}
<head>
<link rel="shortcut icon" href="{% static 'images/favicon.ico' %}" />
I am googling a lot to find the solution. Maybe this is windows or python bug. I am here for getting help. It is creating problem while debuging.

Note that I'm still able to play the audio file my template view, but I can't seek to a specific duration of this file. Any hints as to why this is happening ?
Here's my code for models.py :
class Song(models.Model):
song_name = models.CharField(max_length=100)
album_name = models.ForeignKey(Album, on_delete=models.CASCADE)
song_file = models.FileField(upload_to='songs/', null=True,
validators=[validate_song_extension])
def get_absolute_url(self):
return reverse('music:song-detail', kwargs={'pk': self.pk})
def __str__(self):
return self.song_name
I am using a simple CreateView to accept new entries for this Song model with no form_valid() method, is that the possible cause I'm getting this error ?
when i run my code the printer.py returns the below error
Error: printer.py

I'm sending a file with the following route

It works fine in most desktop browsers and some mobile browsers. But on others it does not, and I get this error
