So, the IP you want users to connect with goes in the host. Then the hub IP goes in the forced host.

And its broken....

Are you using another host?

Please help? I changed it back because it would not let me connect, and when i changed IP forwarding to false it said: INFO disconnected with: Kicked whilst connecting to Hub: If you wish to use IP forwarding, please enable it in your BungeeCord config as well!

I'm sorry? I don't understand, can you tell me what's wrong with the config?

Example config which works:

restricted: false
Creative:
motd: '&cSavCraft&0 -&e Join Today.'

restricted: false
ip_forward: false
online_mode: true

Wait what?
I have to domains

Why is your forced hosts set to that?
It should be the same as Hub

I changed it to \/
And I can't join?
Also what server should I point my custom domain to BungeeCord or Hub?

Btw, "ip-forward" should be false

All good now?
