TimeoutError Youtube API A connection attempt failed because the connected party did not properly respond after a period of time

I'm trying to make a search with youtube API search method. It worked a few days, but since yesterday it started showming me a Timeout Error The part of the code:

def YoutubeSearch():
    # this is used to build our youtube api
    youtube = build('youtube', 'v3', developerKey= 'mykey')
    date_tolook = CalculateDate() #Function to calculate the date to look for 
    request = youtube.search().list(
        type = "channel",
        part = "snippet",
        q = domain_name(ls[15]),
        maxResults = 1
    )
    response = request.execute()
    print(response)
    duration = CalculateVideoDuration()
    if response['pageInfo']['totalResults'] > 0 :
        chanid = response['items'][0]['id']['channelId']
        request2 = youtube.search().list(
            part="snippet",
            type = "video",
            channelId= chanid,
            publishedAfter= date_tolook,
            videoDuration=duration,
            order = "date"
        )
        response2 = request2.execute()
        print(response2)
        if response2['pageInfo']['totalResults'] > 0:
            title = response['items'][0]['snippet']['title']
            videoid = response['items'][0]['id']['videoId']
            request3 = youtube.videos().list(
                part="statistics",
                id = videoid
            )
            response3 = request3.execute()
            print(response)
            numberofviews = response['items'][0]['statistics']['viewCount']
            numberoflikes = response['items'][0]['statistics']['likeCount']
            SendEmail(ls[15], title, numberofviews, numberoflikes)
            CreateCsv(ls[15])

The error:

Libraries i use:

from sendgrid.helpers.mail import Mail, Email, To, Content
from sendgrid import SendGridAPIClient
from datetime import datetime, timedelta
from googleapiclient.discovery import build
from tkinter.filedialog import askopenfile
import tkinter
import customtkinter
import pandas as pd
import sendgrid
import os
import re

So i thinks it's something about the port or it might be from youtube server? I have tried everything i could find on the internet but i failed. Please help. Thanks!
