Question

The technology - Fiddler 4.6x, Chrome 56, Firefox 51, Windo

Answer 1

I was facing similar issue with Fiddler v4.6 and followed these steps:

Fiddler 4.6.1.5+

• Click Tools > Fiddler Options.
• Click the HTTPS tab.
• Ensure that the text says Certificates generated by CertEnroll engine.
• Click Actions > Reset Certificates. This may take a minute.
• Accept all prompts

Fiddler 4.6.1.4 and earlier

• Click Tools > Fiddler Options.
• Click the HTTPS tab
• Uncheck the Decrypt HTTPS traffic checkbox
• Click the Remove Interception Certificates button. This may take a minute.
• Accept all of the prompts that appear (e.g. Do you want to delete these certificates, etc)
• (Optional) Click the Fiddler.DefaultCertificateProvider link and verify that the dropdown is set to CertEnroll
• Exit and restart Fiddler
• Click Tools > Fiddler Options.
• Click the HTTPS tab
• Re-check the Decrypt HTTPS traffic checkbox
• Accept all of the prompts that appear (e.g. Do you want to trust this root certificate)
