Unable to Upload Agent Update Files

Symptom

When attempting to upload agent updates in Netwrix Change Tracker, the following errors appear:

System Error
An unknown error occurred

<number> File(s) failed to upload

Cause

The default maximum file upload size in Internet Information Services (IIS) is too low for the agent update files.

Resolution

Increase the file upload size limit in Web.config:

1. Stop all IIS services by running the following command in an elevated Command Prompt:

   iisreset /stop

2. Open the Web.config file:

   C:\inetpub\wwwroot\Change Tracker Generation 7 (NetCore) Hub\Web.config

3. Modify the <requestFiltering> node to increase the allowed content length:

   <requestFiltering>
       <requestLimits maxAllowedContentLength="250000000" />
   </requestFiltering>

4. Save the changes and start IIS services:

   iisreset /start

5. Log in to the Change Tracker console and reupload the update files.
