title: Server responded: 403. How to get round this issue?
body: <pre><code>from bs4 import BeautifulSoup
  import requests
  
  url = 'https://www.otodom.pl/sprzedaz/mieszkanie/warszawa/'
  
  def get_page(url):
  
      he = {"User-Agent":"Mozilla/5.0"}
  
      response = requests.get(url,headers=he)
  
      if not response.ok:
          print('Server responded:',response.status_code)
      else:
          soup = BeautifulSoup(response.text,'lxml')
      return soup
  
  get_page(url)
  </code></pre>
  
  <p>This is my code where I'm trying to gain access to the website but every time I got "Server responded 403". When I run the first time the code worked perfectly but now something blocking. I've tried almost every manner from a stack, change User-Agent, import  urllib.request, and so on.</p>
  
  <p>Does anyone have some idea what's wrong?</p>
