Transfer packet does not work from a local server to a public server.

When attempting to use a transfer packet to switch from a locally hosted Minecraft server to a public server (or vice versa), the connection fails. The error message indicates that the connection was refused:

```
Connecting to {IP}, {PORT}
Couldn't connect to server
io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: getsockopt: {IP}/{IP}:{PORT}
```

The IP has been verified as accessible through the server list and when connecting to each indivual server.
