Hello, am new to this tool. Am trying to learn how to set break points in other to modify requests and response. I have searched for nvideos, but the ones i have seen are from old version of fiddler with totally different ui. Can someone explain or point me to a video that can assist.

When I use Fiddler to debug my program with CONNECT proxy for mailserver:995 it not work. But I compiled Org.Mentalis.Proxy and it work fine. Why?

After Fiddler return "Connection: close" no more traffic by tunnel.

When I'm trying to install fidder Cert Maker, it cannot seem to detect the Fiddler install, despite the fact that I just installed Fiddler Everywhere 1.1.1. Is there a work around to get it to install?

I use fiddler to review many of the http and https communications from our application. We have a websocket implementation connected to a phoenix/elixir server using the ws prefix. So our url looks like ws://{ip}:4000/socket/websocket. None of the communications from our application to this end point are visible in Fiddler. I can see any and all http and https traffic we're doing, but not the websocket calls. The websocket connections are working and the app is sending and receiving messages correctly, but I'd like to be able to see the messages to monitor this part of the application. Any thoughts would be great. Thank you.

Hello,

i'm getting Network error while trying to sign in at Fiddler Everywhere 1.1.1. See attached file

i'm using my personal network (at home) without proxy. 

Any clue? Thak you

I'm connecting to a site using https which use an invalid certificate, and when I connect to it, I receive a browser warning saying the certificate is invalid, but after selecting the option to proceed I'm able to browse it correlty. Now I want to inspect the traffic to this site using Fiddle, but I'm receiving the following error:

 

fiddler.network.https> HTTPS handshake to 192.168.xx.xx (for #52) failed. System.Security.Authentication.AuthenticationException The remote certificate is invalid according to the validation procedure.

 

How to make Fiddler to trus this remote certificate?

Its like a flash game where you do something, and refresh and do it again and refresh over and over again. Is there way to just do it once, and use fiddler to make it look like we have done it hundreds of times?

I have a dotnet core project (web api) running on port 5000 locally. I then have 2 clients (postman and a android emulator running flutter) that are running, also locally. I have Fiddler running and it's capturing some traffic (teams, firefox, spotify, etc). But when I make a request in postman or in the flutter app on the android emulator, it is not capturing anything.

What do I need to check/do to make this work?
