Hi!

I'm new to Fiddler, I had some success, but there is also an unsolved problem. My setup is:
- An appliance with an integrated webserver. (This appliance is accessible via HTTP only)
- A PC with Fiddler (used as a reverse proxy)
- Another PC with a Browser
All 3 components are in the same network.

I want to use Fiddler for 2 tasks:
- First task is to edit the webpage of the appliance on the fly, I need to remove some content. This works fine, I managed to edit the page with FiddlerScrip. On the PC with the browser I can see the changed webpage.
- Second task: For later use there is a requirement, that this changed webpage is accessible via HTTPS. I tried a lot of settings in Fiddler, but without success. I can't even see any reaction in Fiddlers Session window when I try to access the changed webpage via HTTPS. I assume that the ports are correct, because it works with HTML. Is there a way to solve this problem?

regards
Gerhard

I've been using Fiddler for years, not really messed with the settings, it's just worked.

At the moment I cannot get it to show any local traffic, developing locally in VS2019 and using Chrome. I have no filters on. Is there any setting I should be looking at?

I updated my Fiddler Web Debugger today 11/4/2020 and I am no longer able to open existing Fiddler captures (*/.saz files). When I double click on them nothing opens up in Fiddler. 

 

How can I downgrade my Fiddler to an older version?

When I install this locally on my machine I am prompted to login using a web browser. In the hospital environment I need to use this, there is not internet access. How can I then install the program?

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.
