gspread到Google工作表TimeoutError：[WinError 10060]

Question

连接尝试失败，因为一段时间后连接方未正确响应或连接的主机未响应。

import gspread
from oauth2client.service_account import ServiceAccountCredentials

scope = ['https://spreadsheets.google.com/feeds', 'https://www.googleapis.com/auth/drive']
creds = ServiceAccountCredentials.from_json_keyfile_name('C:/Users/robin/Desktop/work/secret.json', scope)
client = gspread.authorize(creds)

sheet = client.open("python to sheets").sheet1

错误：
