TimeoutError: [Errno 60] Operation timed out

I've created credentials, downloaded it and shared it with my Spreadsheet. I also enable the google drive api and google spreadsheet api. I really want to know what can i do now.

Here is my code,

import gspread
from oauth2client.service_account import ServiceAccountCredentials

scope = ['https://spreadsheets.google.com/feeds']

credentials = ServiceAccountCredentials.from_json_keyfile_name('test.json', scope)

gc = gspread.authorize(credentials)

wks = gc.open("reivewapi").sheet1
reviews = sheet.get_all_records()

I really want to connect to the google spreadsheet. My system is Mojave, don't know if it affects. THANKS for help.
