Fix common Farming Simulator 25 server errors

Most Farming Simulator 25 server problems come from three things: a player whose game, mods or DLC don’t match the server, a mod that breaks loading, or a product key used in two places. Find what you see below, most common first. The Console shows the server’s side of each problem, and its crash helper suggests a fix when it recognises one.

Joining problems

No connection could be established to the multiplayer game

Why: GIANTS says this is usually a network problem, or a player whose game version, mods or DLC don’t match the server.

Fix it:

1. Check that Overview shows the server as Running.
2. Update the game to the newest version. The server updates by default, so an old game can’t connect.
3. Use a steady connection. Mobile hotspots and public Wi-Fi often fail.
4. Turn off any VPN or proxy and try again.
5. Make sure a firewall or antivirus program isn’t blocking the game.
6. Check that the player owns every DLC the server uses.

If only one player can’t connect, the problem is almost always on their side. If nobody can, look in the Console for errors.

The server isn’t in the multiplayer list

Why: the server isn’t running yet, it’s asleep, or the list is filtered.

Fix it:

1. Check that Overview shows Running. After a start, wait a few minutes. A big farm with mods takes up to four minutes to load.
2. Search for part of the server name, not the whole name.
3. Clear the filters in the list, such as ones that hide servers with passwords or mods.
4. Update your game. A server on a newer version may not show or let you in.
5. If you turned on sleep, open the wake link, play.wilderack.com/w/greenacres, and wait for the server to start.

Multiplayer game stops loading

Why: GIANTS says the most common cause is mods that clash with the game or with each other. A weak connection can also stop loading.

Fix it:

1. Give it time on the first join. Big mods download before you load in.
2. Look in the server’s Console for errors that name a mod.
3. Test without mods. In Settings, pick an empty savegame slot, such as savegame2, with no mods, and start the server. If that loads, a mod on your farm is the cause.
4. Switch back to your farm and remove recent mods a few at a time, as in the performance guide.
5. On the player’s side, update graphics drivers and check that antivirus isn’t blocking the game.

Players can’t join after a game update

Why: the server and every player must be on the same game version. After a patch, players who haven’t updated are turned away.

Fix it:

1. Ask every player to update their game.
2. If you pinned a version under Settings > Game version, move it to the newest one. Players usually can’t go back to an older version.
3. Restart the server and check the Console for mods that need an update from their maker.

A mod download fails or never finishes

Why: big mods take a while, and some network setups made large downloads fail. GIANTS fixed one such problem in version 1.25.1.0.

Fix it:

1. Update the game to the newest version.
2. Make sure the player’s computer has enough free disk space.
3. Try joining again.
4. If it still fails, the player can download the same mod from ModHub in the game first, then join.

A friend doesn’t have a DLC the server uses

Why: DLC can’t be downloaded from the server. Every player must own each DLC the server uses.

Fix it: the player buys the DLC, then joins again. Taking a DLC off the server isn’t simple if your farm already uses its machines or map, so make a backup first.

Console friends can’t join

Why: PlayStation and Xbox players can only join when every mod on the server is also on console ModHub. Mods from other sites and PC-only mods keep them out.

Fix it:

1. Open Mods and check each mod.
2. Swap PC-only mods for their crossplay versions, or remove them.
3. Check that console players own every DLC the server uses.

See mods and crossplay for the full rules.

The game password isn’t accepted

Why: the password was changed, or a player typed the admin password instead of the game password.

Fix it: check the game password in Settings. Passwords may care about capital letters. If you changed it while the server ran, stop and start the server so it takes effect. The admin password is only for the admin login after you join.

Key and licence messages

Product key temporarily blocked

Why: the same product key was used on two systems at once in multiplayer. Farming Simulator licences are for one person, so every player needs their own key. This also happens if a server and a player use the same key.

Fix it:

1. Make sure each player has their own copy of the game.
2. Uninstall the game from any other computer where that key was used.
3. Install it on one system only.
4. If the message stays, contact GIANTS support with the key.

The server licence guide explains why a server needs its own licence.

Activation limit exceeded

Why: the key has been activated on the most devices it allows. This is about the player’s own copy, not the server.

Fix it: email GIANTS customer service with the key and the device you want to use. They can check it and reset the activations.

Server problems

The server won’t start or stops while loading the farm

Why: usually a broken or outdated mod, or a mod map that’s missing. A savegame made on a mod map can’t load without that map.

Fix it:

1. Read the last lines in the Console. They often name the mod or map.
2. Check that the map’s mod is in the mods folder and turned on for the savegame.
3. If it started after a game update, remove the newest or largest mods one at a time.
4. If nothing helps, restore the backup made before the update or the mod install from Backups.

The server is slow or stutters

Too many mods, a big mod map or many hired workers are the usual causes. See the performance guide.
