Problem connecting to the server, but I'm only connecting from one computer and only online

[Red_Blok]

Every time I try to connect to my own island, the server says that connection is not allowed and sends me back to the lobby
I am the only computer connected to the server via my network and the only one on neoxacraft minecraft server
