KB: Resolving "Too many request sent" Error in Web Viewer

Solution Details

This error is typically caused by an issue with the ASP.NET Core runtime installation or configuration on your system. You can confirm this by checking the recent logs in your server for the Web UI service, where you'll likely find the error message "Failed to load ASP.NET Core runtime."

The root cause is usually a version mismatch between the ASP.NET Core runtime installed on your system and the Altium On-Prem Enterprise Server (AES) version. To resolve the error we need to make sure that the installed runtime version is compatible with the version AES is built for.

1. Verify your AES version
    Check your current AES version.

2. Ensure compatible .NET version is installed
    The required .NET version is dependent on the AES version. You can find the compatible .NET version for your AES version in the System Requirements documentation.

• • Go to the System Requirements documentation for AES: System Requirements
  • Select your AES version from the dropdown at the top of the page.
  • Refer to the "Additional Software Installed or Configured" section at the end of the page, which specifies the required .NET version.

3. Install the correct .NET version
    If your ASP.NET Core version doesn't match the requirements, download and install the correct version from the Microsoft website: https://dotnet.microsoft.com/

4. Restart services
    After installing the correct .NET version, restart the AES services.

5. Clear browser cache
    Clear your browser cache and cookies before attempting to access the Web Viewer again.
