Here are some steps from the Steam Community users that will help you to resolve this error.

Server Overload:

When many people download mods, the game’s servers can get too busy. This often happens when you’re trying to download or update mods. If you see this error message during these times, it probably means there are too many people trying to use the servers all at once.

You Just wait a bit. As more people finish downloading, the servers will become less busy, and you’ll likely be able to get your mods without any more trouble.

Launcher Repair:

If the error continues despite server needs being normal, it might be necessary to perform a launcher repair. Follow these steps to repair the launcher:

  1. Navigate to the game’s installation folder. This is typically found at: SteamLibrary\steamapps\common\Cities Skylines II\Launcher.
  2. Locate the file named launcher-installer-windows_2023.11.msi and run it.
  3. Choose the repair option when prompted.
  4. After the repair process is complete, launch the game from Steam. If the error continues initially, wait for a minute until a notification appears in the top right corner of the screen. Click “restart” in the notification to try launching the game again.
