blocked by firewall

You try to open a link, but a firewall blocks it dead. It's not the page itself—your network's security sees something suspicious, like an unknown IP or risky content, and slams the door shut. This might happen at work on a corporate network, or when your home router's filters kick in. A VPN could route around it, or you might need permission from your IT team to get through.
