If a player who plays with mods cannot join your Palworld server, check the setting Players may use mods. When it is Off, the server refuses players whose game runs mods. Turn it On, or ask the player to turn their mods off. The setting is On by default, so someone changed it. Not checked on 1.0.5 as of 4 November 2026: the exact message the player sees.
The setting is bAllowClientMod. Pocketpair describes it as “Allow players with mods enabled to join the server.” Its default in 1.0.5 is True.
Turn it on in the panel
- Open the Config Editor page.
- At the top, choose Game settings.
- Find the group Joining.
- Set Players may use mods to On.
- Save.

- Players may use mods
In this picture, set Players may use mods (1) to On, then choose Save.
The game reads the setting when it starts. If the server is running, the page shows “Saved, waiting for the next restart: (names).” with Restart now. A restart disconnects everyone.
Or ask the player to remove their mods
If you want the setting Off, the player must start Palworld with their mods turned off. Then they can join.
Server mods are different
This setting is about mods in a player’s own game. Loafhosts also runs mods on the server itself. That is a separate switch: Turn on server mods on the Mods page. See Palworld server mods. A server with mods on may keep some players out for another reason: Xbox and PlayStation players cannot install mods. See mods for players.
If it does not work
- It still refuses after the change. The server has not restarted. Restart it.
- You set it by editing the file and it changed back. The game writes
PalWorldSettings.iniagain when it stops. Edit it only while the server is stopped, or use the Config Editor. - The setting is On and the player still cannot join. The cause is something else. See Palworld cannot connect. A common one is a different game version: players must run the same version as the server.
- Only one world ignores your change. A world with its own
WorldOption.savuses its own settings. On the World page, choose Use the Config Editor’s settings for it.
