Somebody can not join to my server

Hello everyone.

please I have one question regarding of the hosting of own server. I created the server due to LAN Party but somebody can joint but somebody not.

Who can not so there is the message from the server console. For example player Sebicz_21 cannot connect. It looks like that server kick him automatically. But he can join to another server.

Do you know please how can we fix it?

Thank you in advance

From log - he just cant connect, because CONNECTING without CONNECTED.

Yes but why.... He also can join to another servers. What can I change on the server side?
