Thanks, Nick!

We couldn't find something specific, so at this point I can only hope that I do get this into use with end users and that it JustWorks™️:) If all else fails, i can also document instructions for manual installation of the certificate.

I would say we can mark this feature request as completed, as there is a one-click capability to achieve this in both tools, and if something comes up later, we can perhaps log it separately.

Best,

I tried that, didn't help.

Then I deleted everything under

C:\Users\<my user name>\AppData\Local\Temp\FiddlerEverywhereReporter

which had the funny effect that now a certificate is added to both stores (user and machine) when i use the menu.

The problem is that it does not work, it is likely broken somehow, because the CONNECT request does not manage to connect and get a response, and even more interestingly - this happens to both stores (user and machine).

The netcore.log has this line for each connect attempt

[2025-05-09 17:59:37:941] [Error] [Fiddler] !SecureClientPipeDirect failed: System.IO.IOException Received an unexpected EOF or 0 bytes from the transport stream. for pipe (CN=*.<the actual CN of the real server>, O=Progress Telerik Fiddler, OU=Created by http://www.fiddler2.com)

I tried a colleague's machine and it had the same issue too.

I will also ping my local IT team in case they know what security hardening may eb in place around this, but I can add the cert to the store myself (export it to desktop, double click, ...) so I do have the rights to do it.

Thanks, Nick, I expected 'run as administrator' to be needed but it didn't help, I tried before putting in the post. I also did try restarting mmc, and fiddler couldn't capture the traffic (it didn't go through even, both symptoms of the cert missing).

There is a chance some security hardening on the system is causing this, I guess.

Do you have some logging in Fiddler I can send you that may help see what happened (e.g., to help at least get a better message - such as that the operation failed - if not a fix)? Or maybe procmon?

There is an exception in the netcore.log from C:\Users\<my user name>\AppData\Roaming\Fiddler Everywhere Reporter\logs

perhaps it is from that operation - I first trusted to the user store (worked). But it likely stems from me having done these before and I am not sure it should/would break the machine store trust operation.

I see that 1.2.0 of Reporter got this feature, love that!

But it does not seem to work. It does not trigger the UAC prompt, it does not trigger the confirmation dialog ("are you sure you want to trust this custom rca") that the command to add to the user store triggers, and it does not add the cert to the machine store, even when Reporter is ran as administrator.

Thanks Maria, that button is new (to me, I had not noticed that since the last time i trusted the FE cert).

My primary need is for the Reporter, so I clumped those together.

Best,
Marin
