ClientConnectorError: Cannot connect to host storage.googleapis.com:443 ssl:default

[ShmilyzqChen]

Hi all,

I have encountered a connection error in downloading the llc4320 data since June this year. Could someone help me to solve this?

My script can work normally before June, but breaks down since the error "ClientConnectorError: Cannot connect to host storage.googleapis.com:443 ssl:default" existed.

It seems this error is connected with module "aiohttp", but I reinstalled this module, and it still not works.
My network is normal and has a speed of more than 120MB/s. The python version is Python 3.8. The aiohttp version is 3.8.6.

Partial of my scripts are as follows:
**
from xmitgcm import llcreader
from retry import retry
import numpy as np

import xarray as xr

import datetime as dt
import scipy.io as scio
from dateutil.relativedelta import relativedelta
import os
import netCDF4 as nc

@retry(delay=1)
def read_data(model,face,varstr,kdep,kt):
    print(dt.datetime.now().strftime('%Y-%m-%d %H:%M:%S') + \
          ' try to read data')
    ds = model.get_dataset(
        varnames = [varstr], type = 'faces',k_levels = [kdep])
    region_slice = {'i_g': slice(0, 4320), 'j': slice(0, 4320),
                    'i': slice(0, 4320), 'j_g': slice(0, 4320),
                    'face':slice(face-1,face),'time': slice(kt,kt+24)}
    region = ds.isel(**region_slice)
    varval = np.mean(region[varstr],axis=0).values
    varval = np.squeeze(varval,0)
    return varval

model = llcreader.ECCOPortalLLC4320Model()

varis = ['Theta','Salt','U','V','W']
kdeps = range(0,90)
face = 6
**

The reported error are :

The above exception was the direct cause of the following exception:

Hello， Have you solved the problem？

[ShmilyzqChen]

Hi, actually I'm not. It may be related to the IP address is blocked in China. After I use the vpn in USA, the problem will not occur. But this way is not convenient and wastes too much network resource. Do you have anyother ideas to solve this?
