TotalAgility error: "The resource is not found."

Issue:

After installing either version 8.1 or 2025.2, attempting to launch the Designer or Workspace while logged in with the same account used to install and run the TotalAgility services results in the error: “The resource is not found.”

In addition, the log file shows this error:

Exception thrown by method Agility.Server.Core.Model.Interfaces.Repository.IAssetRepository::GetAsset() [Agility.Server.Core.Model.Assets.Asset GetAsset(Agility.Server.Core.Model.Assets.AssetIdentity): Agility.Server.Common.ErrorHandling.UserException: The specified asset does not exist.

Resolve:

The issue arises when an HTTPS environment is used while the configuration utility is set to HTTP with Manual Authentication. 
First, verify whether your environment is configured for HTTPS or HTTP, and then follow the steps below.
 

1.  Access to TotalAgility Configuration Utility. (TotalAgility\Utilities\ConfigurationUtility\KTAConfigurationUtility.exe)

2. Go to the Web tab > Check if the Inbound Authentication is set to HTTP with Manual Authentication.

3. If it is set to HTTP with Manual Authentication, change it to  HTTPS with Manual and Windows Authentication.

(The default value for TotalAgility is HTTP, so if it needs to be communicated with HTTPS, changes must be made manually.)
