Assetto Corsa Server Troubleshooting

This guide covers the most common Assetto Corsa server issues and how to fix them.

Required Ports

Both must be open. On XGamingServer, ports are handled automatically.

Server Not Appearing in Browser

Fixes:

• Confirm REGISTER_TO_LOBBY=1 in server_cfg.ini
• Ensure HTTP port (8081) is open TCP and UDP
• Wait 1–2 minutes after startup for lobby registration
• Try connecting via direct IP as a workaround

"No Available Slots" When Joining

Cause: MAX_CLIENTS is higher than the number of [CAR_N] entries in entry_list.ini, or the car model name doesn't match.

Fix:

• Count your [CAR_N] entries — you need at least as many as MAX_CLIENTS
• Verify each MODEL= value matches an actual folder in content/cars/

Custom Car Not Loading

Fixes:

• Check that the data/data.acd file exists inside the car folder on the server
• The folder name in content/cars/ must exactly match MODEL= in entry_list.ini and the CARS= line in server_cfg.ini

Custom Track Not Loading / Server Crashes on Track Load

Fixes:

• Verify data/surfaces.ini exists in the track folder
• If the track has multiple layouts, CONFIG_TRACK must match a valid layout subfolder name — or leave it empty for the default layout
• Check capitalization — folder names are case-sensitive on Linux

Players Get Wrong Car

Cause: In pickup mode, players can choose any listed car. Without pickup mode, slots are assigned sequentially.

Fix:

• If you want players to choose their car: PICKUP_MODE_ENABLED=1
• If you want assigned slots: PICKUP_MODE_ENABLED=0 and lock specific GUIDs to [CAR_N] entries

Can't Use Admin Commands

Fixes:

• Make sure ADMIN_PASSWORD is set in server_cfg.ini
• In-game, type /admin YourPassword in chat first
• Admin access is per-session — you must re-authenticate after every reconnect

Server Closes After Race Ends

Cause: LOOP_MODE=0 (default behavior).

Fix: Set LOOP_MODE=1 in [SERVER] to restart sessions automatically after the race.

Players Disconnecting with High Ping

Fix: Add a ping limit to [SERVER] in server_cfg.ini:

MAX_CONTACTS_PER_KM=10

Or limit ping in the Assetto Corsa server lobby settings.

Mod Content Mismatch

Cause: Players don't have the same custom content installed.

Fix: All players must have the exact same custom cars and tracks installed locally. Share download links with your community. Content Manager can help players manage content.
