I have a Python script that scrapes data from CoinGecko. It works perfectly on my laptop but throws an error when I run it on my PC. The script is as follows:

import urllib.request
from bs4 import BeautifulSoup
import pandas as pd
import gzip
import brotli
import io
import time

# Function to get the page content with custom headers
def get_page_content(url):
    req = urllib.request.Request(url, headers={
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.51 Safari/537.36',
        'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',

        'Accept-Encoding': 'gzip, deflate, br',
        'Connection': 'keep-alive',
        'Upgrade-Insecure-Requests': '1'
    })
    response = urllib.request.urlopen(req)
   
    # Handle different content encodings
    if response.info().get('Content-Encoding') == 'gzip':
        buf = io.BytesIO(response.read())
        data = gzip.GzipFile(fileobj=buf).read()
    elif response.info().get('Content-Encoding') == 'br':
        data = brotli.decompress(response.read())
    else:
        data = response.read()
   
    return data

        div_element = soup.find('div', class_='tw-mb-6 lg:tw-mb-12')
        if div_element:
            html_table = div_element.find('table')
            if html_table:
                df = pd.read_html(str(html_table))[0]
                df = df.loc[:, df.columns[1:-1]]  # Adjust the columns as per your requirement
                return df
            else:
                print(f"No table found in the specified div for URL: {page_url}")
        else:
            print(f"Specified div element not found for URL: {page_url}")
    except Exception as e:
        print(f"An error occurred for URL {page_url}: {str(e)}")
    return None

# Base URL
base_url = 'https://www.coingecko.com/en/coins/1/markets/spot?page='

# DataFrame to collect all data

# Start page

    print(f"Processing {url}")
    retries = 0
    while retries < max_retries:
        try:
            df = extract_table_data(url)
            if df is not None:
                all_data = pd.concat([all_data, df], ignore_index=True)

                break  # Successfully retrieved data, break out of the retry loop
            else:
                print(f"No data found on page {page}, stopping.")
                consecutive_errors += 1
                break
        except urllib.error.HTTPError as e:
            if e.code == 404:
                print(f"HTTP Error 404 on page {page}. Stopping.")
                consecutive_errors += 1
                break
            else:
                print(f"HTTP Error on page {page}: {e.code}. Retrying...")
                retries += 1
                time.sleep(retry_delay)
        except Exception as e:
            print(f"An error occurred on page {page}: {str(e)}. Retrying...")
            retries += 1

        break

    page += 1

# Save the complete DataFrame to CSV in the specified path
save_path = r'C:UsershamidDownloadsCrypto_Data_Table.csv'
all_data.to_csv(save_path, index=False)
print(f"All data saved to '{save_path}'")

When I run it on my PC, I receive the following error:

Processing https://www.coingecko.com/en/coins/1/markets/spot?page=1
An error occurred for URL https://www.coingecko.com/en/coins/1/markets/spot?page=1: nonnumeric port: 'port'
No data found on page 1, stopping.
Processing https://www.coingecko.com/en/coins/1/markets/spot?page=2
An error occurred for URL https://www.coingecko.com/en/coins/1/markets/spot?page=2: nonnumeric port: 'port'
No data found on page 2, stopping.
...
Stopping due to 5 consecutive errors.
All data saved to 'C:UsershamidDownloadsCrypto_Data_Table.csv'

I’m not using a proxy, and the same script works fine on my laptop. What could be causing this issue on my PC, and how can I resolve it?. Thanks in advance.
