Project Zomboid server settings and options

A dedicated Project Zomboid server.

Options you choose at checkout

• Game Build: choose Build 42 (the current version) or Build 41 (the older version, which many existing mods still target).

Start and connect

1. Press Start and wait until the status says Online.
2. Find your address and port on the Network page. See Network and ports.
3. In the game, use its direct connect or add-server option with that address and port.

Some games use extra ports, for example to list the server in a browser. If players cannot see or reach your server, open a ticket and we will check the ports. See Contact support.

Settings you can change

These are the settings shown on your Startup page. Only settings that can be safely edited are listed.

Change a setting

1. Stop your server.
2. Open Startup in the left menu and find the setting under Server Variables.
3. Change the value, save, and start your server.

See Startup settings.

Files the panel keeps up to date

Each time your server starts, the panel writes your server’s port and address into: none. If a value you set in those files keeps changing back, that is why. Change it with the settings above, or open a ticket.
