Ark Server App Id Specified By Server Is Invalid

This error message in ARK: Survival Evolved indicates a mismatch between the game server's reported Application ID (App ID) and the client's expected App ID. This prevents your client from connecting to the server. Let's break down why this happens and how to fix it.

Understanding the Problem

The App ID is a unique identifier for each version of ARK. If the server is running a different version (or a modified version) than your client, this error will pop up. This discrepancy can stem from several sources:

Outdated Client: Your game client might need an update to match the server's version.
Outdated Server: The server's ARK version may be outdated or improperly configured.
Modified Server: The server might be running a modified version of ARK, incompatible with the standard client.
Incorrect Configuration: There might be a typo or error in the server's configuration file specifying the App ID.

Troubleshooting Steps

Follow these steps to resolve the "Ark Server App ID Specified by Server Is Invalid" error:

1. Update Your Game Client

The most common solution is to ensure your ARK: Survival Evolved client is up-to-date. Open your game client (Steam, Epic Games Store, etc.) and check for updates. Restart the client after the update completes.

2. Check the Server's Version

Contact the server administrator. They need to verify their server is running a compatible version of ARK and properly configured. They should check their server's App ID and ensure it matches a legitimate ARK version.

3. Verify Server Configuration Files

If you're administering the server yourself, carefully review the server's configuration files (usually located within the server's installation directory). Look for any typos or incorrect settings related to the App ID. Ensure the App ID is correctly set to match the installed game version.

4. Consider Modified Servers

If you are connecting to a non-official server, be aware that modified servers may require a specific client or mods that are not compatible with the standard game. Check the server's requirements or information for any special instructions.

5. Reinstall the Game (Last Resort)

If all else fails, a clean reinstallation of the game client might help. This ensures all files are properly installed and not corrupted. Remember to back up any important save files before doing this.

Still Having Issues?

If you've followed these steps and still encounter the error, consider seeking additional assistance from the ARK community forums or the support channels for your game platform (Steam, Epic Games Store). Providing details about the server you're trying to connect to will help others assist you effectively. Remember to include details about your game version and any modifications you've installed.
