Cloudflare Error 520 (2026)

Error 520 is a Cloudflare response that indicates the origin server returned an unexpected, empty, or invalid response. In most cases, the issue is on the server side, not the user's.

Common Causes of Error 520:

- Application failure or backend server crash
- Server overload (CPU, memory, or database)
- Oversized or malformed HTTP headers
- Firewall blocking or conflicts with Cloudflare
- DNS or SSL configuration issues
- Invalid responses from the origin server

️ How to Fix It Quickly:

- Refresh the page and clear your browser cache (if you're a user)
- Check server logs (Apache / Nginx / application)
- Make sure your firewall isn't blocking Cloudflare IPs
- Verify DNS records and origin server configuration
- Test the origin server directly (bypassing Cloudflare)
- Reduce the size of HTTP headers and cookies
- Check server load and available resources (CPU / RAM)

How Web Scraping Works

Web scraping automatically retrieves web pages, extracts the required elements from HTML, and stores structured data for analysis.

Key Steps:

- Send an HTTP request to a website
- Receive HTML or JSON data
- Extract information using CSS selectors
- Save the results to a database or file

️ Which Proxies to Use:

- Rotating residential proxies → large-scale data collection
- Static residential proxies → long-term scraping sessions
- Mobile proxies → websites with advanced anti-bot protection
- Datacenter proxies → fast, low-risk scraping tasks

Reliable web scraping depends on accurate parsing logic, controlled request rates, and the right proxy infrastructure.

Virtual Numbers for Business (2026)

Virtual numbers help companies create local accounts, receive SMS messages and calls, and work with services and customers across different countries.

What to consider:

- Number type: physical SIM card or VoIP
- Country coverage and supported platforms
- Code delivery speed and rental period
- Refund policy for failed activations

️ Which service to choose:

- SMS services → one-time registrations and verifications
- Long-term rentals → permanent business accounts
- VoIP platforms → calls, virtual PBX systems, and CRM integrations
- API services → automating verification workflows in products

For international businesses, a phone number alone isn’t enough. A reliable setup also includes a region-appropriate IP address, quality checks, and a secure payment method.

Virtual Number for Telegram (2026)

The “Invalid Number” error usually appears when Telegram identifies a number as public, inactive, or as a low-reputation VoIP number.

What to check:

- Whether the number is active on the carrier’s network
- Whether it is flagged as VoIP or a public SMS number
- Whether the number’s region matches the connection region
- Whether you can regain access to the line later

️ What helps:

- A number from a real mobile carrier → more reliable registration
- Residential or mobile IP → consistent regional signals
- Two-step verification → additional protection against SIM-swap risks
- Dedicated line → lower risk of the number being reused

A working phone number may solve the registration error, but the long-term security of a Telegram account depends on maintaining control of the line and enabling an additional password.

Selenium Proxy Authentication on Servers: Fixing 407 Errors, Geolocation, and Broken Sessions

I thought my Selenium script was production-ready because it worked perfectly on my laptop. Then I moved it to a server

Сonnection errors, proxy auth issues, different geolocation, broken sessions. All of it was ruining my workflow. So what did help? It was treating the proxy layer as infrastructure instead of a random Chrome argument.

First, I test the proxy outside Selenium with curl. If I get 407 Proxy Authentication Required, I know the problem is credentials or proxy configuration. Then I wire authentication properly. In Python, selenium-wire can handle authenticated proxies. In Node.js, proxy-chain is useful when you need a local forwarding proxy.

After that, I check environment consistency. If the exit IP is in London while the browser reports another timezone, locale, or obviously different settings, debugging becomes much harder. Chrome DevTools Protocol can help keep timezone configuration consistent with the test environment. Don’t debug Selenium, proxy authentication, browser settings, and target-site behavior at the same time.

️ My workflow now is:

curl → verify proxy → Selenium integration → browser config → actual test
