RimWorld Together: Connecting to the Server

Q: What does a “Mod Mismatch” or connection drop after joining mean?

It usually means your client doesn’t have exactly the same (forced) mods enabled as the server. Compare your enabled mods with the server’s mod list.

RimWorld Together: Connecting to the Server

Requirements

To connect to a RimWorld Together server, you need:

The base game RimWorld via Steam
The RimWorld Together mod including Harmony (both can be subscribed to via the Steam Workshop)
Optional: the server password, if your server is password protected

Warning

Forced Mods If your server requires certain mods (see Installing Mods), you must also enable these client-side beforehand — otherwise the connection will fail.

Activating Mods in the Game

Before connecting, the RimWorld Together mod must be active in your client:

Subscribe to the RimWorld Together mod in the Steam Workshop — choose "Subscribe to All" when subscribing so Harmony and all other dependencies are installed automatically.
Launch RimWorld and open Mods from the main menu.
Move Harmony and RimWorld Together into the enabled mods area.
Click Auto sort mods to ensure the correct load order, then confirm with Save and Apply.

Getting Server Details

You need all relevant info to connect to your server. You can find this in the dashboard of your game server. Important details include:

IP address and port
Server name
Server password (optional)

With this information, you should be able to find your server and ensure you’re connecting to the right one.

Connecting to the Server

Start RimWorld with the RimWorld Together mod enabled (see above).
Select Play Together from the main menu.
Enter a username and confirm with Confirm.
Enter your server’s IP address and port together (e.g., 123.45.67.89:25555) and confirm again with Confirm.

Tip

Use the exact IP address and port from your ZapX dashboard, including the colon between them.

Possible Issues and Solutions

Connection Fails Immediately

Check that you entered the IP address and port correctly without spaces in the format IP:Port, and that your server is actually running in the ZapX dashboard (under the Console tab).

"Mod Mismatch" or Connection Drops After Joining

This usually means your client does not have exactly the same (forced) mods enabled as the server. Compare your enabled mods with the server’s mod list, see Installing Mods.
