Astroneer Server Not Showing

Having trouble finding your universe? If your newly rented Astroneer dedicated server is missing from the Favorite Servers list, or if players can see it but still cannot join, work through the quick troubleshooting checks below.

Server not in the list

1. Confirm the server is running. Log in to the AleForge Panel, open the Console, and verify that the startup process finished without any errors.
2. Verify your connection details. Navigate to the Network tab and copy your server’s IP and port again. Make sure to format it exactly as IP:port when entering it into the Server URL field.
3. Re-add the server. In Astroneer, open the Server List, click Add Dedicated Server, and paste your address. (Note: The server nickname you choose is only a local label on your PC).
4. Restart your game client. If the Favorite Servers list remains empty, fully quit Astroneer, relaunch the game, and attempt to add the server again. Still stuck? Try loading into any single-player save, returning to the main menu, and adding the server one last time.

Unable to join after the server is listed

If your server is visible but rejecting connections, check the following common configuration issues:

Issue	What to do
Password Protection	Ensure players are typing the exact ServerPassword. If this value is blank in your settings, the server has no password. See how to set a password.
Admin/Owner Setup	OwnerName must match the player’s exact Steam name, and OwnerGuid must be set to 0 before that player joins for the first time. See how to set the owner.
Wrong Active Save	Ensure ActiveSaveFileDescriptiveName only includes the name before the $ in the filename. See how to upload a save.
Settings Reverting	Always stop your server before editing the AstroServerSettings.ini file. Any edits made while the server is actively running will be overwritten and discarded.
Whitelist / Allowed List	If DenyUnlistedPlayers is set to true, only approved players can join. Stop the server and set it to false if you want to open the server back up.
Xbox or Microsoft Store	These versions of the game are restricted and can only join System Era preferred partners. However, Steam and PlayStation players can connect to our global hosting network seamlessly using the IP and port.
Version Mismatch	Ensure your game client is up to date. The dedicated server and the game must run the exact same version to connect successfully.

Still stuck?

Check the Console for any red startup errors. If you cannot spot the issue, contact the AleForge support team with your server name and the exact time the connection failed—we are here to get your Astroneer server hosting back on track.
