This appears to be working if Fiddler is showing a tunnel. Although, I am not entirely certain from the information provided. My first guess is that the application requires a specific certificate. Since it thinks the Fiddler Root Certificate is the client certificate and it doesn't match what the server expects then it will not connect. In order to troubleshoot this I'll need more information. Are you able to provide the following?
1. Output of the Session. See the Create a Session Archive Zip (SAZ) documentation.
2. Output of the Fiddler Log tab. Select everything and right-click to save the output to a file. See below screenshot fore visual reference.
Please let me know if you can provide the above information. Thank you and I look forward to your reply.
