Buenas, estoy intentando replicar este ejemplo de GitHub, pero me salen dos errores y no consigo solucionarlo, me pasa desde tres ordenadores distintos y se supone que funciona a la perfección. Lo errores son estos:

line 955, in getaddrinfo  
for res in \_socket.getaddrinfo(host, port, family, type, proto, flags):  
socket.gaierror: [Errno 11001] getaddrinfo failed

y

line 1351, in do\_open  
raise URLError(err)  
urllib.error.URLError: \<urlopen error [Errno 11001] getaddrinfo failed\>

El enlace del ejemplo completo es este:

Descargo el contenido completo en una carpeta y ejecuto example.py

El código de ese módulo principal es:

```auto
from ESIOS import *
from matplotlib import pyplot as plt
import urllib #lo he añadido yo
from urllib.request import urlopen #lo he añadido yo
import ssl
ssl._create_default_https_context = ssl._create_unverified_context

if __name__ == ' __main__':
    # Request arguments
    end_ = datetime.datetime.today()
    start_ = end_ - datetime.timedelta(days=30)
    # The token is unique: You should ask for yours to: Consultas Sios <consultasios@ree.es>
    token = '615e6d8c80629b8eef25c8f3d0c36094e23db4ed50ce5458f3462129d7c46dba'
    esios = ESIOS(token)

    # esios.save_indicators_table()
    # indicators_ = [600, 672, 673, 674, 675, 676, 677, 680, 681, 682, 683, 767, 1192, 1193, 1293]
    indicators_ = list()
    # indicators_.append(682) # Precio de Regulación Secundaria subir
    # indicators_.append(683) # Precio de Regulación Secundaria bajar
    indicators_.append(600) # Precio mercado SPOT Diario
    # indicators_.append(1293) # Demanda real
    indicators_.append(551) # Eólica T.Real
    # names = esios.get_names(indicators_)
    df_list, names = esios.get_multiple_series(indicators_, start_, end_)

    df_merged = esios.merge_series(df_list, names) # merge the DataFrames into a single one

    df = df_merged[names] # get the actual series and neglect the rest of the info

    # plot
    fig, ax1 = plt.subplots()

    df[names[0]].plot(ax=ax1) # demand
    ax1.set_xlabel('time')
    ax1.set_ylabel('MW')

    # secondary axis
    ax2 = ax1.twinx()
    df[names[0::]].plot(ax=ax2) # others
    ax2.set_ylabel('€')

plt.show()

```

Y el error que arroja es este, alguna idea de cómo solucionarlo?? he probado todo lo que he visto por google sin éxito, gracias!:

Parece que está tratando de acceder a internet y no puede. La llamada de `getaddrinfo` es la base de convertir un nombre de dominio a una IP…

¿Tenés internet donde estás ejecutando eso?

Buenas! He probado con 3 ordenadores distintos y tres conexiones distintas para replicar el ejemplo que os pongo. Has probado si te sale el ejemplo de git? Yo pensaba que lo mismo habían modificado algo en la url
