Access denied errors at certain websites

Based on my knowledge, Costco (and some other major websites) use bot protection services (like Akamai or Cloudflare) to block suspicious traffic. This can mistakenly flag legitimate users as threats due to:

• Suspicious or misconfigured IP address ranges
• VPN or proxy use
• Overly aggressive browser extensions (like ad blockers, privacy tools)
• Older or modified browser user agents
• ISP-level caching or DNS anomalies

Also, if you can’t download Chrome, this could indicate a broader connectivity or filtering issue, possibly:

• A misconfigured firewall, antivirus, or router
• DNS or SSL filtering at the ISP or network level
• Outdated system root certificates

So I have some recommend steps to Try and Fix

1. Restart modem/router This may get you a new IP if it's dynamic and unflagged.

2. Try incognito/private mode or a different browser Avoid extensions in this mode.

3. Disable VPN or proxy, if any VPNs are often flagged as suspicious traffic sources.

4. Flush DNS cache Open Command Prompt (as admin) and run:

ipconfig /flushdns

5. Switch to another DNS like Google or Cloudflare:

• Google: 8.8.8.8 and 8.8.4.4
• Cloudflare: 1.1.1.1 and 1.0.0.1

6. Try a mobile hotspot If it works via mobile but not your usual network, your ISP IP range may be blocked.

7. If Chrome download is blocked: Use this direct link: https://www.google.com/chrome/ Or try from a different network/device and transfer via USB.
