@FRANZ_LYNCH I have the notion you are using Norton VPN when this happens. Please review the following if that is the case:

AI Overview

If Cloudflare and Imperva are repeatedly blocking you from websites you used to visit without issue, it means your current web connection or browser setup is triggering their automated bot-detection systems. These services are Web Application Firewalls (WAFs); they don’t block you because they want to, but because your connection resembles automated spam or a cyberattack. [1, 2, 3, 4]

:hammer_and_wrench: Step-by-Step Fixes

  1. Turn Off Your VPN or Proxy

If you use a Virtual Private Network (VPN) or an iCloud Private Relay, temporarily disable it. [1, 2]

  • Why: VPN servers share IP addresses among thousands of users. One user on that platform agreed that if another person using the same VPN IP address acts maliciously, Cloudflare or Imperva will blacklist that IP, blocking you by association. [1, 2]
  1. Check and Disable Browser Extensions

Extensions that modify your web requests are the most common culprits for endless “Verify You Are Human” loops. [1, 2]

  • The Test: Open an Incognito / InPrivate window and try to access the site. If it works, an extension is causing the problem.

  • What to disable: Temporarily turn off ad blockers, privacy protection tools (like Ghostery), or User-Agent switchers. [1, 2, 3, 4, 5, 6]

  1. Clear Specific Site Cookies and Cache

Corrupted data can sometimes cause verification scripts to fail continuously. [1, 2]

  • Go to your browser settings, search for Cookies and Site Data, and delete the specific cookies associated with the blocked website.

  • Alternatively, on a Reddit discussion about Cloudflare, one user explicitly recommended simply deleting your cookies for the blocked site and reloading. [1, 2, 3]

  1. Reboot Your Wi-Fi Router

Most home internet services utilize dynamic IP addresses. [1, 2]

  • Unplug your Wi-Fi router for 30 seconds and plug it back in.

  • Why: This forces your Internet Service Provider (ISP) to assign your router a fresh, clean IP address, instantly shedding any bad reputation your old IP might have gathered. [1, 2, 3, 4, 5]

  1. Verify Your Device is Clean

Run a deep malware scan using a trusted antivirus or antimalware program. If your laptop or phone has background malware sending silent spam, firewall networks like Imperva will actively shut down your access to the web. [1, 2]

:speech_balloon: What to do if nothing works

If the block remains, look at the error screen for a Ray ID (Cloudflare) or a Reference ID (Imperva). This indicates that the specific website’s owner has configured an overly strict security rule that is catching you by mistake. Some users discussing this issue on the Cloudflare Community Forum agree that your best course of action is to contact the website operator directly and share that Ray ID so their IT team can whitelist your connection.
