python gspread connection time out when writing to

here's my existing connection code, which works fine

json_key = json.load(open('path/to/json.js')) 
scope = ['https://spreadsheets.google.com/feeds']
credentials = SignedJwtAssertionCredentials(json_key['client_email'], json_key['private_key'], scope)
gc = gspread.authorize(credentials)

but after 10 mintutes or so my connection will time out.

after reading around a bit i came across the use of this in the connection code,

headers = gspread.httpsession.HTTPSession(headers={'Connection':'Keep-Alive'})

but i'm not sure how include into my existing connection code. what is the correct way to include it? the examples i've seen are not the same as my connection code above, and the examples specify a password that's not in the json connection file that i'm using

here's an an output of the error. sometimes they differ slightly. but it's all down to the same connection time out

If the time is exceeded, you can call a Function to Reconnect to the Database. I have provided a sample code snippet that you can incorporate within your program.

import gspread
from oauth2client.service_account import ServiceAccountCredentials

from datetime import datetime
from datetime import timedelta

def connect_database():

    scope = ['https://spreadsheets.google.com/feeds', 'https://www.googleapis.com/auth/drive']
    creds = ServiceAccountCredentials.from_json_keyfile_name('client_secret.json', scope)
    client = gspread.authorize(creds)

    workbook1 = client.open("File_Name")
    w1 = workbook1.worksheet("Sheet1")
    w2 = workbook1.worksheet("Sheet2")

    return w1,w2

program_start_time=datetime.now()

if datetime.now() > program_start_time + timedelta(minutes=10):
    worksheet1, worksheet2 = connect_database()
    program_start_time = datetime.now()   #Resets the Program Start Time
