Although the properties are true and complete, Example: the player I banned on my server a can enter my server b. How do I ban that player from all my servers?

Note: The server keys on the website are active and the config file is set like this  "Bans on your network": true,

That seems to work now, however, I am now having the opposite issue as you, "Bans on your network": false, on all my servers, but players banned in server A are still kicked while connecting to server B...
