What does this mean?

webchat.freenode.net normally uses encryption (SSL) to protect your information. When Chrome tried to connect to webchat.freenode.net this time, webchat.freenode.net returned unusual and incorrect credentials. Either an attacker is trying to pretend to be webchat.freenode.net, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.

Network errors and attacks are usually temporary, so this page will probably work later. You can also try switching to another network.
