Если Cloudflare не пускает на сайт, это может быть связано с проблемой с DNS или проблемой с конфигурацией на стороне сервера.
Давайте рассмотрим возможные причины, которые приведут к этому сценарию.
Проблемы с DNS могут возникнуть, если в настройках DNS указан неправильный IP-адрес или если DNS не синхронизирован с сервером.
В конфигурации на стороне сервера может быть проблема с настройками безопасности, например, если включен режим "блокировать IP-адреса" или если настроены неправильные правила безопасности.
Challenges of Website Parsing
Parsinhg websites with Cloudflare can be a real challenge, especially if you don't consider the nuances. Obeying Cloudflare's protection is a real puzzle.
One of the biggest obstacles is avoiding Cloudflare's security measures. Cloudflare's protection is a genuine head-scratcher.
Cloudflare's defense is especially tricky if you're not aware of the subtleties. If you don't account for the subtleties, you'll likely encounter difficulties.
The most common pitfalls include the complexities of parsing sites with Cloudflare. The complexities of parsing sites with Cloudflare are a major hurdle.
Server Load and Performance
A sudden influx of requests can completely paralyze a website's work and render it useless for a significant period.
Imagine if your website is hit with a massive surge of requests - hundreds or even thousands per minute. This can be catastrophic, causing server overload and potentially leading to a prolonged downtime.
To prevent this, websites often employ measures to protect against server overload, such as limiting the number of requests from a single source.
This is crucial, as server overload can be devastating, causing a website to grind to a halt and leaving users frustrated and disappointed.

Protection and Security
Cloudflare uses two approaches to protect sites: passive and active bot detection. Passive detection is not mentioned in the article section, but active detection is.
Active detection involves interacting with the user to determine whether they're a human or a bot. Cloudflare uses several methods for this, including CAPTCHA, which is a familiar concept for many users.
CAPTCHA is a simple yet effective way to distinguish between humans and bots. It typically involves solving a puzzle, such as identifying images of cars or transcribing text from an image.
Cloudflare also analyzes user behavior to determine whether it's natural or mechanical. This includes monitoring mouse movements, keyboard inputs, and click patterns.
Another method used by Cloudflare is collecting data about the user's browser. This includes unique characteristics such as screen size and installed browser extensions.
Here are some methods used by Cloudflare to detect bots:
- CAPTCHA
- Анализ действий пользователя
- Сбор данных о браузере
- Анализ API среды
Cloudflare may also display a Challenge Page or run JavaScript checks to further verify the user's identity. These mechanisms are designed to be imperceptible to humans but challenging for bots.
In summary, Cloudflare's active bot detection methods are designed to analyze every detail of a user's behavior to protect sites from automation.
Troubleshooting and Solutions
If your site is using Cloudflare, it's likely inaccessible to Russian users and losing traffic.
To fix this, you can temporarily disable Cloudflare's proxy. This will make your site accessible again, but it also makes it vulnerable to DDoS attacks.
You can also check your DNS settings and switch to Russian DNS servers if needed.
If you're using foreign DNS providers, consider switching to Russian ones.
To permanently solve the issue, experts recommend migrating to a Russian CDN and anti-DDoS services. This will take time and money, but it will help you adapt to local rules and keep your audience.
Here are some possible solutions to get you started:
- Temporarily disable Cloudflare's proxy
- Check and switch to Russian DNS servers
- Migrate to a Russian CDN and anti-DDoS services
- Replace scripts and fonts loaded from Cloudflare domains with alternative sources
Incorrect Proxy Settings
Incorrect Proxy Settings can be a major obstacle in web scraping. Using low-quality proxies that have already been blacklisted significantly increases the risk of being detected.
Cloudflare is particularly vigilant and will block requests coming from these proxies immediately. This can lead to a failed scraping operation and wasted time.
Incorrect proxy settings can be a common mistake, especially for those new to web scraping. It's essential to ensure that your proxies are properly configured to avoid this issue.
Using high-quality proxies that are regularly updated can help minimize the risk of detection. This is a crucial step in maintaining the integrity of your scraping operation.
What Is User-Agent and Why Change It?
User-Agent is a string that's sent in an HTTP request and contains info about your browser, operating system, and device. It's what servers use to figure out who's making the request - a desktop, smartphone, or maybe even a bot.
This string can look something like this: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36.
Cloudflare might block your request if it notices something fishy with your User-Agent, like it not matching your real browser.
What Happened and Why
The issues with Cloudflare started in the fall of 2024, when Roskomnadzor (RKN) began selectively blocking individual Cloudflare services by filtering traffic.
Cloudflare's use of the TLS ECH technology, which allows for encrypted client hellos, is a key factor in this issue. This technology is a means of bypassing access restrictions on prohibited information in Russia, which is against Russian law.
In February 2025, Cloudflare was added to the register of organizers of information distribution (ORI), which requires them to store data and hand it over to Russian authorities. However, since Cloudflare doesn't have a presence in Russia, this requirement is difficult to fulfill.
In April 2025, RKN recommended that Russian website owners stop using Cloudflare's CDN service, but few heeded this warning. Then, in June 2025, RKN added a significant portion of Cloudflare's IP addresses to the unified register of blocked resources and notified telecom operators to filter them.
Large Russian providers, including Rostelecom, MTS, Megafon, Vimpelcom, and MGT, began restricting traffic to Cloudflare's servers on June 9. This led to massive disruptions and loading issues for many services, affecting both domestic and foreign websites that were partially or completely inaccessible to Russian addresses.
Cloudflare confirmed that the restrictions are applied by local providers and are outside their control, making it impossible for them to restore reliable and high-performance access to their products and protected websites for Russian users.
RKN struggled to block websites hidden behind Cloudflare, but the service refused to comply with Russian laws, ignoring requests from regulators and law enforcement. Pointed blocking didn't work either.
The main issue is that Cloudflare doesn't store logs or IP addresses, making it impossible for RKN to identify and block specific users. This is why RKN had to resort to blocking entire IP ranges.
Here are some possible reasons for the issues with Cloudflare:
- Technical works on servers
- Infrastructure attack or DDoS attack
- Access blocked by Roskomnadzor or antivirus software
If you're experiencing issues with Cloudflare, try the following:
- Check your DNS settings and consider switching to a local DNS provider
- Temporarily disable Cloudflare's proxying to restore access
- Migrate to a Russian CDN for long-term solutions
- Check your third-party dependencies and replace them with alternative sources if necessary
Login Issue with Personal Account
If you're having trouble accessing your Cloudflare personal account, it's likely due to a simple mistake.
First, double-check that you've entered your login and password correctly, as incorrect credentials are often the culprit.
Sometimes, the issue might be with your browser, so make sure you're running the latest version.
If you're still having trouble, it's possible that the problem is on the server side, indicated by a 502 or 504 error code.
These errors can be caused by server overload or a DDoS attack, and in such cases, it's best to wait for the issue to be resolved by the Cloudflare support team.

Common Issues and Errors
CAPTCHA errors can lead to Cloudflare blocking your requests. This is because CAPTCHA solvers, while useful for website parsing, are not perfect and can make mistakes or be used too frequently.
Errors in CAPTCHA solving can trigger Cloudflare's security measures, causing it to block your requests.
CAPTCHA solvers can be accessed too often, leading to Cloudflare suspecting malicious activity and blocking your requests. In some cases, this can even result in a temporary block on the CAPTCHA service itself.

Why Cloudflare Blocks
Cloudflare blocks access to your site for a reason. It's trying to protect you from malicious traffic.
Cloudflare checks the User-Agent string in your HTTP requests to determine the type of device making the request. This string contains information about your browser, operating system, and device.
If Cloudflare detects a suspicious User-Agent, it may block the request. This is because the User-Agent string doesn't match the real browser.
Cloudflare is looking for anomalies in the User-Agent string. If it doesn't match the actual browser, the request might be blocked.
Guides and Tutorials
If your site is hosted through Cloudflare and you're experiencing issues with users from Russia, there are a few things you can try.
First, you can temporarily disable Cloudflare's proxy. This will immediately restore access to your site, but it also makes it vulnerable to DDoS attacks.
To do this, remove the "orange cloud" icon from your DNS settings. This will allow traffic to flow directly to your server.
Alternatively, you can switch to a Russian DNS provider. This might help resolve the issue, but it's worth noting that this is just a temporary solution.
If you're looking for a more permanent fix, consider migrating to a Russian CDN. This will require some time and money, but it will allow you to comply with local regulations and retain your audience.
Lastly, be sure to check your site's external dependencies. If you're using scripts or fonts hosted on Cloudflare domains, they might be blocked. Try replacing them with alternative sources if possible.
Here are some steps to take:
- Temporarily disable Cloudflare's proxy
- Switch to a Russian DNS provider
- Migrate to a Russian CDN
- Check external dependencies and replace them with alternative sources
Conclusion and Summary
Parsing data from Cloudflare-protected sites is a complex task, but it's doable if done correctly. Modern tools like anti-detect browsers, proxy services, and automation scripts can simplify the process.
It's essential to ask yourself some questions before attempting to parse a site: is it the only way to get the data you need? Perhaps the site has a public API that provides similar information. Or, you can try buying the data legally, which will not only save you time but also avoid potential consequences.

Cloudflare blocking is not a technical glitch, but rather a continuation of the policy of localization and control. Website owners will have to prepare an alternative plan, consider local rules, and stay vigilant.
The best way to protect your site from Cloudflare blocking is to make it capable of surviving without it. Users should focus on finding domestic alternatives to blocked services. Unfortunately, the current situation is leading to internet segmentation and limiting access to websites without unnecessary hassle.
