This might be better to post in the Technical Issues forum. The Player Help forum is mostly for general questions about the game, events, or game mechanics. You should also provide more details than that. Your ISP, a traceroute, and possibly CoH Helper information would help. If you don't know what those are, search for them on the internet or the forums.
The login server could also be down and the issue could resolve itself. If you get the same error after waiting an hour, post again in the Technical Issues forum.
