Configure Fiddler Classic

- In the Port box, provide the port Fiddler is listening on (8888).
- Leave the Authentication slider to Off.
Decrypting HTTPS Traffic from an iOS Device
- Navigate to http://WorkstationIP:8888/FiddlerRoot.cer to download the FiddlerRoot certificate to the iOS device.
- Open the FiddlerRoot.cer file and install.
- Once the certificate is installed, navigate to Settings > About > Certificate Trust Settings and enable the toggle for DO_NOT_TRUST_FiddlerRoot under the section ENABLE FULL TRUST FOR ROOT CERTIFICATES.
- Reproduce the issue.
