What is error code 1020?

Error code 1020, known as the access denied error, occurs when Cloudflare blocks an IP address attempting to access a website. This measure protects against threats like malicious attacks and aggressive web scraping by restricting certain IPs to ensure website security.

What is causing error code 1020?

Error code 1020 is usually caused when the server detects a massive amount of requests from the same IP address. There are multiple reasons for this:

  • Using scripts that overload the website
  • Using browser extensions that are sending too many requests
  • Using bots or tools like ChatGPT
  • Having a shared IP address that gets blocked because of other users on the same IP address
  • Living in a country or region blocked by the site owner
  • And ultimately, because of web scraping

Let's take a look at how you can fix this error. There are two ways. The first applies when you're just visiting some site and get this error. In that case, continue reading the following section. But if you get this error when web scraping, click here.

How to fix error code 1020

1. See if the website is working

First, you should check if the website is working. This will eliminate aby problem on your end.

For that, you can use services such as DownDetector. Go to their page and enter the website you’re having a problem with.

If the website works well for others, continue with the following steps to fix the error code 1020.

2. Try other pages on the site

If the website works correctly, check other pages on the same website to eliminate the possibility that you're trying to access a broken page.

Search for the website name in Google and click on other pages. Eventually, you can also use the site: command in Google to find all pages from the domain to check them. The syntax is as follows:

3. Restart your web browser

Another easy fix is to restart your browser. Close all browser windows, and make sure you also close the browser in the background. In Windows, you can do so in the “Show hidden icons” menu.

Another way is to find the process in the Task Manager and close it.

Sometimes, the VPN services can cause errors such as error code 1020.

5. Deactivate browser extensions

Some browser extensions can cause error code 1020. To eliminate this possibility, you can try to deactivate them. Here is a guide on how to deactivate browser extensions for Google Chrome:

10 tips on how to bypass Cloudflare error 1020 when web scraping

  1. Slow down your requests: By reducing the speed of your scraping activities, you can avoid hitting rate limits or appearing suspicious and behaving like a bot.
  2. Rotate IP addresses: Use proxy servers to distribute your requests across multiple IP addresses. This will help solve the problem of Cloudflare IP banning.
  3. Respect robots.txt: Always check the robots.txt file of a website. It provides guidance on what you can and can't scrape. If you don't need to scrape a particular page, skip it.
  4. Use headers wisely: Mimic real browser behavior by using user-agent strings and headers that won't immediately flag your scrapers as bots.
  5. Consider using scraping services: Tools and services designed for web scraping, such as the Apify platform or open-source web scraping libraries Crawlee and Scrapy, can help you scrape websites protected by Cloudflare and other security measures.
  6. Implement CAPTCHA-solving: if the website you're scraping uses CAPTCHAs as part of its access control, you'll need to find a way to solve those CAPTCHAs automatically.
  7. Use browser automation tools: Tools like Selenium, Playwright, or Puppeteer can simulate real user interactions more accurately, making it harder for Cloudflare to distinguish between a bot and a human user.
  8. Dynamic timing and request patterns: Adjust the timing of your requests dynamically to more closely mimic human browsing patterns.
  9. Use residential proxies: These proxies are less likely to be blocked because they come from real ISP-assigned IP addresses.
  10. HTTPS and TLS fingerprinting: Modifying the TLS fingerprint of your requests to match those of common web browsers can help avoid detection based on network traffic analysis.
