Hi Namrata,

This is most likely additional security measures enabled by the website owner to block a Man-In-The-Middle attack. For example, Certificate Pinning checks the certificate signature for validity on the server and if the presented certificate doesn't match it responds with an error.

As a result, this doesn't appear to be an issue with Fiddler Everywhere. However, we do appreciate and welcome your feedback. I would also like to encourage your participation in the Fiddler Insiders Program.

In the meantime, please let me know if you need any additional information. Thank you for using Fiddler Everywhere.
