Ошибка подключения к файлу api.openweathermap.org?

Я написал этот код, чтобы получать обновления погоды в указанном городе: 

import tkinter as tk
from tkinter import *
import pyowm
from PIL import ImageTk, Image

win=tk.Tk()


#frame_for_showing_weather.
weather_frame=Frame(win,bg='black',width='300',height='300')
weather_frame.place(x=0,y=0)


weath=Label(weather_frame,font=('Agency',100),fg='white',bg='black')
weath.place(x=10,y=10)

temp1=''
owm=pyowm.OWM('a1bdf2e4609febbedaf0fcc823e3d527')

def obs():
    global temp1
    observation = owm.weather_at_place('Barisal,BD')
    w=observation.get_weather()
    temp2=w.get_temperature('celsius')
    if(temp2!=temp1):
        temp1=temp2['temp']
        weath.config(text=str(int(temp1))+chr(176))        
    weath.after(60000,obs)
obs()


win.mainloop()

Но через некоторое время в моей оболочке произошла большая ошибка:

пожалуйста, кто-нибудь подскажите, почему произошла эта ошибка и как ее можно исправить!

Если вы хотите просто игнорировать время ожидания сокета, вы можете переписать функцию obs, чтобы перехватить это исключение, например: 

from socket import timeout

def obs():
    global temp1
    try:
        observation = owm.weather_at_place('Barisal,BD')
        w=observation.get_weather()
        temp2=w.get_temperature('celsius')
        if(temp2!=temp1):
            temp1=temp2['temp']
            weath.config(text=str(int(temp1))+chr(176))
    except timeout as e:
        print "socket timeout."
        pass
    weath.after(60000,obs)

Это может быть все, что вам нужно.

Я не знаю, как работает OWM, возможно, вам придется закрыть его и снова открыть, чтобы получить свежий сокет.Вы можете сделать это в блоке кроме.Добавьте 

global owm

в вашу функцию и в блоке исключений повторите строку: 

owm=pyowm.OWM('a1bdf2e4609febbedaf0fcc823e3d527')

, которая создаст новый объект OWM, предположительно закрывая старый и открывая новыйодин.
