If you are experiencing intermittent connection problems, you can change the connection type on the login box. In the Server drop-down box, change from Automatic server selection to the Anti Firewall option.
The Anti Firewall option uses server alt1.chessclub.com and port 443 instead of server chessclub.com and ports 5000-5099. This helps some users with connectivity issues because ISP's often prioritize port 443 (web browsing) above other ports.
