I'll ask ctaoistrach to check logs on his server (7OXICiTY).
Creating own server is not that easy actually, because your server must be accessible from the internet, otherwise nobody can connect (connection timeout error). If you want to host your own public server, you need to ask your internet provider about public IP address first. Then you will also need to forward port of your server on your home router. If your server gets listed here on the website, it means you did everything right and players can connect. In the GameSpy times, it was possible to create own server even without doing these things, and some (but not all) players could still connect. With CryMP, your server is accessible for either everyone or nobody.
