Unturned server loading not working

What mods have you downloaded / what does your WorkshopDownloadConfig.json file look like?

I checked the server log you posted, and it looks like you haven't downloaded any mods. Buak is a modded map – make sure you've installed it per the yellow error message!

The WorkshopDownloadConfig.json file is located in the root of your server's folder. (Along with other files/folders, such as the Server folder, Players folder, and Config.json file.)

Thanks for sharing. To clarify - Buak is not an official/vanilla map. The "Map" command wasn't working because you do not have the map installed.

You have to download the map from the Steam Workshop in order to use it on your server. The instructions for doing so are noted in the yellow error message that appeared in your server console, in addition to the server hosting documentation.

3000549606 is the map's file ID. You can add this to the "File_IDs" property of the config file in order to download that map. The same applies to any mod that you want to install on your server. For example, you might configure that property to look like this:

  "File_IDs": [
    3000549606
  ],

For more information, I recommend referring to this part of the server hosting documentation: https://docs.smartlydressedgames.com/en/stable/servers/server-hosting.html#how-to-configure-server

None of these errors would cause the mod to stop downloading / all of those errors are safe to ignore. Note that our support site (and the modding/server documentation, depending on the type of error) can be used to look up what various error messages or warnings mean!

Would you mind sharing a link to the server's log file again?
