I have a tuned fiddler. It great was working before today morning. 
I already had such a problem and it solved itself (i don't know how). I wasn't change settings, it just stopped decrypting.

Hi Artem,

Thank you for using the Fiddler Forums. In order to troubleshoot this fully, we'll need additional information. Can you provide the following items?

1. Output of the Fiddler Log Tab.

2. Session Archive Zip of the HTTPS sessions.

3. A screenshot of the Sessions Pane with the sessions highlighted.

4. Any additional information (logs, screenshots) that you might find relevant.

Additionally, if the HTTPS requests are from a 3rd party application or service this could be caused by Certificate Pinning. Note that if this is the case, there isn't a workaround available as this type of decryption is unsupported in Fiddler.

Please let me know if you need any additional information. Thank you and I look forward to your reply.

Regards,
