Fiddler can't track traffic but httpAnalyzer can (traffic looks like websockets)

I need to explore the traffic from one program.

The program makes something like a connection through the WebSockets.

Fiddler displays this:

Request Headers: `CONNECT 144.***:443 HTTP/1.0`

Response: `HTTP/1.0 200 Connection Established`

End empty body.

But httpanalyzer displays full information after that response, and that information continues flowing. Very likely like WebSockets (one connection and receive more answers).


And fiddler display zero traffic.

How can I explore such traffic through the fiddler?

At this moment, the Fiddler Everywhere client does not show WebSocket messages but from the provided screenshots it appears that you are using the Fiddler Classic application - I've just posted an explanation about the WS functionality in the Fiddler Classic in. this forum thread.

Update: The latest version of Fiddler Everywhere (3.0.1) now supports capturing and displaying WebSocket traffic (alongside other perks like HTTP/2 capturing, improved UI and performance, etc.).
