According to data that was reported by W3Techs, CloudFlare is used by most of the world’s top websites to protect their servers from DDoS (Distributed Denial of Service) attacks and malicious bots.
Page challenges.cloudflare.com is the gate of the digital security guard. His job is to ensure that visitors who come are real humans, not robots or automatic scripts with malicious intent.

The main cause of being stuck on the CloudFlare page
To Unblock challenges.cloudflare.com Effectively, we have to diagnose the disease first. Based on technical discussions on various IT forums and user reports, here are the main culprits:
Bad IP reputation: If you use public Wi-Fi or free VPN, it is likely that the IP address you are using is already marked as “spam” by CloudFlare because it is used by thousands of people at once.
Aggressive browser extension: The use of AdBlocker, UBlock Origin, or privacy extensions such as Privacy Badger often blocks the script CloudFlare uses to verify your browser.
Out of sync hours and dates: This is trivial but fatal. If the clock on your laptop or cellphone does not match the global server time, the SSL security certificate will be considered invalid.
Old browser: Using a very old version of Chrome or Firefox makes you fail to pass modern security tests.
ISP problem: Sometimes, your own internet service provider (ISP) is experiencing interference Routing to the CloudFlare server.

Popular DNS comparison table:
| DNS provider | Primary DNS | Secondary DNS | Excellence |
| CloudFlare | 1.1.1.1 | 1.0.0.1 | Fastest, High Privacy, Sync with Challenges.CloudFlare |
| 8.8.8.8 | 8.4.4.4 | Very stable, rarely down | |
| OpenDNS | 208.67.222.222 | 208.67.220.220 | Family Safety Features (Family Shield) |

Turn off or replace the VPN server

2. Install the “Privacy Pass” extension
This is an ironic but effective solution. Privacy Pass is a browser extension supported by CloudFlare. This extension lets you complete the captcha once, then get a digital “token”. This token will be used automatically when you visit another site that is protected by CloudFlare, so you don’t have to check it over and over again.
3. Check malware on your device
According to reports from various cybersecurity companies such as Kaspersky or Malwarebytes, if your computer is infected with a botnet virus, your computer may secretly send thousands of requests to the internet without your knowledge.
