Go to Main -> Preferences -> Connections, click the Server tab. Leave host as login.icq.com and below set the port to 443. For Proxy settings, check Using Firewall and below check Using proxy and choose HTTP. Below that check Keep connection alive. Hopefully this will solve it, did so for me many times.

Hope this helps.
