How do I connect to my server?

Every server gets an address of the form yourname.cobbly.net. You can copy it from the dashboard card or the top of the server page.

In Minecraft: Multiplayer → Add Server, paste the address into the Server Address field, and leave the port alone. There is no port to add — the address already points at the right place.

If the server is asleep, it will show as Sleeping in your list rather than offline. That is normal, and it is not an error.
