Performing a Fiddler trace


Troubleshooting of connectivity problems with our web services may require diagnostic data not available in product diagnostic logs. This wiki provides steps to capture web traffic using a free web diagnostic tool from Telerik called Fiddler.

Steps to accomplish

*** Before you begin please open the task manager and end task the Bentley.Licensing.Service.exe process first, then end task the Bentley.Connect.Client.exe.

Please perform the following steps to perform a web capture of a problem:

  1. Download FiddlerCap by clicking the Download Installer button in the lower leftdo not use the Download Now button in the upper right.
  2. Run the installer, and click the Install button.
    Note: Installation does not require administrator access.

  4. In the window that appears, select the "Decrypt HTTPS traffic" checkbox. This enables us to analyze web traffic to and from our servers which is typically encrypted for security.

  5. An informational alert appears explaining that a security certificate must be temporarily installed to decrypt HTTPS traffic. Click OK to dismiss the message.
  6. Click the Yes button in the dialog that appears to temporarily install the security certificate.
    Note: You will be prompted to remove the security certificate later when FiddlerCap is closed.
