ARP Proxy

There are several ways to bypass Telegram blocking, the most popular of which involves installing a proxy. There are bots in the messenger that allow you to get such a working tool, such as @socks_bot, for free. By running the bot and selecting a location to connect, you can get an IP address, port, username and password. To activate the proxy, go through "Settings" to "Data and Drive" and then to "Proxy Settings." After enabling "Use proxy settings", enter the corresponding data in the specified fields.

The term "public" should be understood to mean open proxy servers. That is, they can be used by all users without exception. They can be insecure and are often quite overloaded, so the connection speed or response time when using public proxies can be very slow.

To hide the Chrome browser during Selenium C# tests, you can use the --headless flag when initializing the ChromeDriver. The --headless flag runs Chrome in headless mode, which means it will run in the background without a visible user interface.

Here's an example of how to set up a headless Chrome browser using Selenium C#:

First, install the necessary NuGet packages for Selenium WebDriver and ChromeDriver:

Install-Package OpenQA.Selenium.Chrome
Install-Package OpenQA.Selenium.WebDriver

Then, create a new C# class for your Selenium test, for example, HeadlessChromeExample.cs.

Write the test code:

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using System;

namespace HeadlessChromeExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // Set the path to the ChromeDriver executable
            string driverPath = "/path/to/chromedriver";

            // Create a new instance of the ChromeDriver with the --headless flag
            IWebDriver driver = new ChromeDriver(driverPath, new ChromeOptions()
            {
                // Set the headless mode to true
                Headless = true
            });

            // Navigate to the webpage
            driver.Navigate().GoToUrl("http://example.com");

            // Perform your test actions here

            // Close the WebDriver instance
            driver.Quit();
        }
    }
}

Run the test:

You can run your test using your preferred C# IDE or by using the command line. If you're using a console application, you can run the test by pressing Ctrl + F5.

This should help you set up a headless Chrome browser using Selenium C# and execute your test without the browser being visible. Make sure to replace "/path/to/chromedriver" with the actual path to your ChromeDriver executable and "http://example.com" with the URL of the webpage you want to test.

If you can't download images in Scrapy:

- Check the image pipeline configuration in settings.py.
- Verify HTTPS compatibility and install the certifi package if necessary.
- Confirm the correctness of XPath or CSS selectors for image URLs.
- Ensure image URLs are in the correct format; log URLs for inspection.
- Handle redirects by setting REDIRECT_ENABLED = True.
- Check and set appropriate HTTP headers in your Scrapy spider.
- Adjust the CONCURRENT_REQUESTS setting to avoid server restrictions.
- Verify correct configuration of the ImagesPipeline.
- Inspect the downloaded images in the specified IMAGES_STORE directory.
- Implement exception handling in your spider to catch download errors.

For Telegram, it is recommended to use paid proxy servers of the Socks5 protocol. These proxies provide the user with data protection and high and stable connection speed. Telegram developers recommend using servers from European countries.
