Astroneer server problems

Common Astroneer server problems. See Astroneer settings.

I cannot find my server in the game

Why it happens: Astroneer dedicated servers are joined by adding their address and port in the game. The Public IP must also be right.

How to fix it:

1. Press Start and wait for Online.
2. In Astroneer, choose the server option and add the address and port from Network. See Network and ports.
3. Use the format address:port.
4. Check the Public IP setting below.

Public IP is wrong or blank

Why it happens: Astroneer needs to know the server’s public address. Public IP (PUBLIC_IP) is the value written into the game’s config.

How to fix it:

1. On Network, note the primary IP address. If it only shows a hostname, open a ticket.
2. On Startup, put that IP in Public IP.
3. Save and restart. If you are unsure which value to use, open a ticket.

Cannot connect, “Connection failed” or timed out

Why it happens: Wrong address or port, the server is still starting, or a version mismatch.

How to fix it:

1. Check the server is Online.
2. Re-copy the address and port from Network.
3. Make sure the game is up to date, see below.
4. See Can’t connect to any game server.

Version mismatch after an Astroneer update

Why it happens: Players update the game before the server updates.

How to fix it:

1. Keep Automatic Updates (AUTO_UPDATE) at 1 and restart the server.
2. Ask players to update the game on their platform.

I am not the owner or admin of my server

Why it happens: The developers’ server guide says the first player to connect with the Steam name listed as the owner becomes the server’s owner.

How to fix it:

1. On Startup, set Server Owner Name (OWNER_NAME) to your Steam username and Server Owner Guid (OWNER_GUID) to your Steam ID.
2. Restart the server, then join.
3. If it was claimed by someone else, open a ticket.

Where is my save and how do I back it up?

Why it happens: Saves are kept in the server’s Astro folder.

How to fix it:

1. Use Backups to create a backup before big changes. See Backups.
2. Game data is kept under the Astro/Saved folder in Files. You can download files from there.
3. Stop the server before restoring a save.

Lost progress after a crash

Why it happens: Astroneer saves periodically, so recent progress can be lost in a crash.

How to fix it:

1. Open Backups and restore the latest one.
2. Set up a scheduled backup. See Schedules.

Server crashes on start

Why it happens: A bad config edit, a corrupted save, or a failed update.

How to fix it:

1. Read the end of the Console.
2. If you edited AstroServerSettings.ini or Engine.ini, undo the change.
3. Set Public IP properly, and restart.
4. If it continues, restore a backup or open a ticket.

My config edits keep reverting

Why it happens: The panel may rewrite AstroServerSettings.ini and Engine.ini on start from the Startup values. Edits to these files made while the server is running are also not kept, so stop the server first.

How to fix it: Change the value on Startup instead: Public IP, owner, password, name.

Players cannot join with a password

Why it happens: Server Password (SERVER_PWD) must match exactly, and is case sensitive.

How to fix it: Re-enter the password on Startup, save, restart, and give players the new value.

Server name does not show as expected

Why it happens: Server Name (SERVER_NAME) defaults to a generic name.

How to fix it: Change it on Startup, then restart.

Out of memory

Why it happens: Large bases and many players use memory.

How to fix it: See Out of memory and Upgrade.

Players cannot connect even though the server is online

Why it happens: Astroneer dedicated servers need a change on each player’s own computer. Without it, the game cannot join the server.

How to fix it: Every player who joins must do this on their own PC:

1. Close Astroneer.
2. Open the file Engine.ini, found at %LocalAppData%\Astro\Saved\Config\WindowsNoEditor\Engine.ini.
3. Add these two lines at the end of the file, then save it:

   [SystemSettings]
   net.AllowEncryption=False

4. Start Astroneer and join again.
