Introduction
Your Mount & Blade II: Bannerlord game server isn’t showing up in the server list, you can’t join it, or your settings aren’t taking effect? Don’t worry—most issues have a simple cause. Here are the most common problems and how to fix them quickly yourself.
FAQ
Frequently asked questions
Check that your server is running and has logged in with a valid server token. Also, search for the exact name entered in the Server Name field on the Configuration tab.
Usually, the game and server versions don’t match. Update your game. If the server has a password, players must enter it when joining.
Changes only take effect after a restart. The server name, game mode, passwords, and player count always come from the startup parameters in ZapX, so corresponding lines in custom_server_config.txt are skipped.
The map entered in the Map field isn’t available on the server or is misspelled. Your server then automatically uses the game mode’s default map.
No. In Bannerlord, the Console only displays the log. Use the Admin Panel or Server Dashboard for admin commands, and custom_server_config.txt for persistent settings.

Mount & Blade II: Bannerlord
Problems and solutions
The most important tool for troubleshooting is your game server’s Console. In Bannerlord, it only displays the log; you can’t enter commands there. However, you can see what your server does as it starts, including the name, game mode, and map it starts with, as well as where an error occurs.
If your server won’t start at all or shuts down shortly after starting, see our guide Server won’t start.
Server list and connection
Server doesn’t appear in the Custom Server List
First, check the Overview to see if your server is running and the Console to see whether it has successfully logged in. Your server won’t appear in the list without a valid server token.
Also, search for the exact name you entered in the Server Name field on the Configuration tab. After a restart, it may take a short while for your server to appear in the list again.
Can’t join because of the game version
The game and server must use the same version of Bannerlord. Older versions aren’t compatible with each other. Update your game through your gaming platform. If your game is newer than the server, please contact our support team.
Players can’t join because of the password
If a Server Password is set on the Configuration tab, all players must enter it when joining. To make your server public, clear the field, save your changes, and restart your server.
A player has been banned
Players banned through the Admin Panel can only rejoin after you restart your server. Restart your server to lift all bans. Kicked players, on the other hand, can rejoin immediately.
Settings and maps
My changes aren’t being applied
Changes made on the Configuration tab and in custom_server_config.txt only take effect after a restart. After saving, select Restart Now or restart your server from the Overview.
The server name, game mode, passwords, and player count always come from ZapX. For this reason, lines containing ServerName, GameType, AdminPassword, GamePassword, or MaxNumberOfPlayers in custom_server_config.txt are skipped. Change these values in the startup parameters instead.
Server starts with a different map
If the map entered in the Map field isn’t available on the server or is misspelled, your server automatically uses the game mode’s default map. The Console will show a message such as map '...' does not exist on the dedicated server. Check the exact spelling and make sure the map is compatible with your game mode. Official maps only work with the game mode they were created for.
Admin login doesn’t work
Join your server by right-clicking it in the Custom Server List and selecting Join as Admin. Use the password from the Admin Password field on the Configuration tab. If you’ve changed the password, restart your server for the change to take effect.
Server Dashboard won’t open
The Server Dashboard in the Overview is only accessible while your server is running. If it won’t start, see our guide Server won’t start to find the cause. To log in, you’ll need the password from the Admin Password field. If the Dashboard remains stuck in the “Ending” state after End Mission, restart your server. Learn more in our Server Dashboard guide.
Can’t change the map and game mode in the Admin Panel
You can only change the game mode and map in the Admin Panel if automatic map switching is enabled on your server. To enable it, add maps to custom_server_config.txt using add_map_to_automated_battle_pool and include the enable_automated_battle_switching command, then restart your server. See our Game modes and maps guide for details.
Performance
Lag or crashes during large battles
How much performance your server needs depends on the game mode and player count. Small matches like Skirmish or Duel require far fewer resources than large battles in Siege, Team Deathmatch, or Captain. TaleWorlds itself runs small matches with 2 CPU cores and 4 GB of RAM, and large battles with 4 CPU cores and 8 GB. Keep an eye on usage in the Overview, reduce the number of bots if needed, or upgrade your server directly using the resource tiles.
DDoS and other network threats
Game servers can be targeted by attacks that flood them with traffic, causing lag or disconnections. ZAP-Hosting has built-in protection systems to protect your server from common attacks. If you suspect an attack, contact our support team.
Preventive measures
Regular backups can save you a lot of stress. We already back up your game server automatically every day. With ZapX Pass, you can also create your own backups at any time and restore them with one click—with ZapX Pass Pro, you can even automate backups on your own schedule. Also, keep track of your server token’s expiration date so you can renew it before it expires after 3 months.
Conclusion
These steps should help you solve the problem. If not, don’t hesitate to contact our support team—we’re here every day and happy to help! 🙂
