I agree that I think there may be something blocking Fiddler from capturing any traffic. This could be something proprietary that was built into the application or the web traffic is using HTTPS
Although, in order to understand this I would need the following information.
The software being used to inspect it's traffic
The Session Archive Zip (SAZ)
file and the Fiddler Log
Once I receive the above information I will be able to investigate more.
Please let me know if you need any additional information. Thank you and I look forward to your reply.
