When I attempt to browse to one of my company's websites with Fiddler running, I get the following error on the CONNECT:
fiddler.network.https> HTTPS handshake to site.mycompany.com failed. System.IO.IOException Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. < An existing connection was forcibly closed by the remote host
Fiddler is running under the administrator account and can access most other HTTPS sites (ie, Outlook, Facebook, other company sites). Things I've tried:
- Installing the Fiddler certificate under Local Machine (that compounded the problem, couldn't access the Telerik site then)
- Tried running IE as administrator
- Added CONFIG.oAcceptedServerHTTPSProtocols = System.Security.Authentication.SslProtocols.Ssl3; in the Main function in Fiddler script.
