Windows 11 is blocking some websitesSolved

Yes, I actually dealt with the same problem last week. In my case, it turned out to be the Ip configuration that was causing the issue. Resetting it fixed everything. 

Just open Command prompt with admin permission and run these commands one at a time: 

• ipconfig /flushdns – Clears the Dns cache, which removes stored domain name information. Useful if websites aren’t loading correctly. 
• ipconfig /registerdns – Refreshes the computer’s DNS settings and re-registers its hostname with the Dns server. Helps fix name resolution issues. 
• ipconfig /release – Releases the current IP address assigned by the DHCP server, essentially disconnecting the device from the network. 
• ipconfig /renew – Requests a new Ip address from the DHCP server. Helps restore network connectivity if the Ip lease has expired or is invalid. 
• netsh winsock reset – Resets the Winsock catalog (which manages network socket connections) to default settings. Useful for fixing internet connectivity problems caused by corrupted network configurations.

Then, restart your system. 

After the restart, all the blocked websites started working for me. It’s a quick way to refresh the system’s network settings and fix most Dns or IP-related issues. 

Same here. These commands have saved me more than once, especially after updates or when switching Wifi networks. It’s like giving your network settings a fresh start. 

Also, double-check if you’re using a Vpn or a third-party DNS. Sometimes those can interfere too. But usually, the reset does the trick.
