Good day,
so im running the trial versions, and it seems like i have to configure every device i want to monitor individually?
cant i point my router to fiddler and through that see all my connected devices?
I'm evaluating Fiddler Everywhere, and trying troubleshoot a java application.
Initially Fiddler shows a warning that it cant decrypt HTTPS, so I install the root certificate into Arch and trust it, set Fiddler to use system proxy, and then set up the application to point to Fiddlers proxy.
The warning in Fiddler then disappears, so it gives the impression I've done everything right
At this point it can show HTTPS connections (although they are shown as HTTP, and METHOD is always CONNECT, rather than the GET I was expecting to see).
It's also then able to show HTTP(S) headers, but never the actual decrypted response or request body
Any help appreciated thanks
When I close fiddler, I can access to outlook; while using fiddler, I fail to visit it with the error message below:

I'm trying to use fiddler v4.4.8.4 in my ubuntu 14.04 virtual machine to capture https connections, and I get "secure connection failed". Of course, when I close fiddler or don't check cature https connects, firefox works well.
I've done operations below:
1. Export root certificate to desktop, update proxy settings in firefox, import and trust fiddler certificate in firefox.
2. In firefox about:config, set:
3. I've used openssl to recreate a crt ver. certificate, added it into /usr/share/ca-certificates/mozilla, and reconfigured it.
Does anybody know how to solve this problem?

Hello.
On Windows it works perfectly fine for me. However on Linux fiddler everywhere seems to be unable to catch traffic from windows games running through proton. Is there any way to get that working?

How to fix this
Im also try to edit fiddler rules
static function OnBeforeRequest(oSession: Session) {
if (oSession.HTTPMethodIs("CONNECT") &&
oSession.HostnameIs("142.251.12.102"))
{
oSession["X-OverrideCertCN"] = "google.com";
}
Still failed
What i do is in this tutorial : https://anasfanani.id/post/redirect-all-linux-traffict-to-httphttpssocks-proxy-fiddlerburp

Hello,
Does Fiddler Everywhere support websockets?
If it does how can I enable it?
Thank you in advance.
