How to Trust the Fiddler Root Certificate

Environment

Service Third-party product

Description

When the Fiddler Root certificate on the machine is not trusted, you cannot capture HTTPS traffic and Fiddler logs do not contain any information about Telerik Platform/AppBuilder requests.

The article provides general steps for trusting the Fiddler Root certificate on your local machine. This is normally done automatically when installing Fiddler, but certain environment configurations disallow it and in such cases, you need to manually install and trust the certificate.

Solution

  1. Run Fiddler and go to Tools -> Fiddler Options.
  2. On the HTTPS page, click Export Root Certificate to Desktop.
  3. In Windows Explorer, navigate to Desktop and double-click FiddlerRoot.cer.
  4. Click Install Certificate, install it for the Local Machine and click Next.
  5. Select Automatically select the certificate store based on the type of certificate.
  6. Click Next and then Finish.
  7. After you close the "The import was successful" alert, go back to Fiddler's Tools -> Fiddler Options -> HTTPS.

The Fiddler Root certificate is now trusted on your machine and you can capture HTTPS traffic.
