Https gives ERR_CONNECTION_RESET in Fiddler as well as .NET.

Can someone explain to me why enter this link in Chrome

while Fiddler is running does ERR_CONNECTION_RESET error occur?

NOTE:

  • I have successfully configured Fiddler to "Decrypt HTTPS Traffic" and used my own certificate for that. I see traffic from other HTTPS sites. Only this domain is behaving strangely.

  • I tried to use the HttpWebRequest class in .NET to request a simple GET for this link with no parameters and no headers, and I get "Connected connection was closed: an unexpected error occurred while submitting." an error that is almost certainly the same ERR_CONNECTION_RESET from Chrome.

  • I've tried inserting all sorts of headers like Keep-Alive (checked both true and false) in my GET request to no avail.

  • I am not using proxies when coding in .NET.

Any ideas?

I had this problem for all https sites and solved it by dropping Fiddler certificates from the Tools> Fiddler Options> HTTPS dialog. After resetting the certificates, it is important to reinstall the Fiddler root certificate in Firefox and / or other software that does not use the OS certificate store if you want to debug https sites in it.

Stuck with the same problem. Installed the newest version of Fiddler v4 and disabled the antivirus program - it started working.
