2. Use HTTPS instead of HTTP

Since the error 451 unavailable for legal reasons occurs when using the HTTP protocol, try using HTTPS instead. If the page also has an SSL certificate, your request will force the HTTPS page instead of loading the HTTP version.

HTTPS Everywhere forces your browser to load only HTTPS pages

If this solution works for you, consider installing HTTPS Everywhere, a browser extension that forces pages to load HTTPS if they exist.

3. Change your DNS servers

  1. Go to Network Connections, select your network interface, and click Properties
  2. Select Internet Protocol Version 4 (TCP/IPv4) and press PropertiesChange the properties of your IPv4 network
  3. Select Use the DNS server addressesChange your DNS server addresses
  4. At Preferred DNS server, write 8.8.8.8 (Google Public DNS)
  5. At Alternate DNS server, write 8.8.4.4 (Google Public DNS)
  6. Press OK and try to access the blocked page

Instead of Google Public DNS, you can also try OpenDNS (208.67.222.222 preferred, 208.67.220.220 alternate) and Cloudflare (1.1.1.1 preferred, 1.0.0.1 alternate). Those are free and public DNS servers.

In some cases, governments can block DNS requests instead of specific IP addresses. To test this theory, you can change your DNS servers and try to get past error 451 unavailable due to legal reasons.

4. Use a proxy server

A proxy server redirects your browser traffic to another IP address. So you can use it to hide your true IP address and switch to another one that’s not blocked by your government (in another country).

It’s worth a shot if you want to fix HTTP error 451 unavailable for legal reasons.

Use a free proxy server to bypass error 451 unavailable due to legal reasons

Try accessing the blocked page using a free online proxy service like Hide.me Proxy, Hidester Proxy and Croxy Proxy. But there’s a small chance that your government has already identified and blocked those public IP addresses.
