IRC what does it stand for?
It stands for Internet Relay Chat

In order to clarify this problem, we need more information. For example the error message.

Try other IRC servers. If no IRC server works, check whether your firewall has blocked the ports.

Do not use a proxy or any other encryption methods

That depends on your concerns.

Usually Windows users mIRC and Linux users currently use HexChat
