How to set a dark theme on Fiddler Classic?

Hello, i have app using fiddler, and i have problem like in Subject. Proxy in windows settings turn on like normal but i can't see result of fiddler proxy. Im using windows 11. There's any way to fix that? Thanks! :) 

After update updating Edge browser to version 124.0.2478.51，when access website I get  "Your connection is not private" 

I have configured Windows to trust Fiddler's root certificate.

I set fiddler " !listen 8889 *.acs.org " and set " fiddler.network.https.SetCNFromSNI true"  It works well  before update edge browser.

After update edge when i access pubs.acs.org it is ok.

but when i access pubs.rsc.org i get   "Your connection is not private" 

 I think this is because someing make fiddler  cannot automatically match certificates .

Please help me fix it ,thanks so much!

 

When accessing the nature website via fiddler, if you check Decrypt HTTPS traffic, error 403 forbidden will appear, unchecked resolve https can be accessed normally. As you can see in the picture below:

Is there currently a way to get the Filter back?

When I try to enable the System Capture it says: Capturing not enabled, please try again! 
I removed the Filter manually, but now I cannot add it back, I won't get asked. I checked if there is some local Storage, but couldn't find any.

Hi everyone,

I have an .net framework 4.7.2 C# WPF app running which also has a little .net 3.5 app inside it.

This is running 1500 computers in australia and has been for 18 months.

Today we started getting reports of computers having 'crashes'

Debugging has provided this info:

section: created rest options System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel.

What we have now found out is that it is Windows 7 clients all being affected.

Importantly:

Postman and google chrome can access the api

JUST the .net seems ot be having issues.

After seeing this I have downlaoded fiddler (for first time) and we are seeing a handshake issue:

fiddler.network.https> HTTPS handshake to www.mydomain.com.au (for #710) failed. System.Security.Authentication.AuthenticationException A call to SSPI failed, see inner exception. < The message received was unexpected or badly formatted

Win32 (SChannel) Native Error Code: 0x80090326


But then when i booted fiddler im also seeing the same issue:

[Fiddler] The connection to 'api.getfiddler.com' failed.  <br />System.Security.SecurityException Failed to negotiate HTTPS connection with server.fiddler.network.https&gt; HTTPS handshake to api.getfiddler.com (for #1) failed. System.Security.Authentication.AuthenticationException A call to SSPI failed, see inner exception. &lt; The message received was unexpected or badly formatted

Win32 (SChannel) Native Error Code: 0x80090326                                       

 

 

So maybe the fiddler API is in fact having the same connection issue as I do, but maybe thats not really going to be noticed because its an update checker for their API but mine is my whole app??

 

Any ideas would be appreciated.

 

hi there

on windows 2022 server when i close fiddler or stop capture traffic

running apps can nor connect tls 1.2

i always get errors for service connecting until start capturing.

What should I do to make the system work properly when the program is closed?

 

Thaks for your help :)

I just need to sync the last decent, tolerable version of Evernote one more time: https://www.reddit.com/r/Evernote/comments/1cico6e/solutions_for_syncing_the_legacy_v6_client/

How can I do this?  I can't find a way to change the user-agent globally for running programs under WINE.  It's supposedly possible under FIDDLER but I'm new. :(  Help?  I searched the documentation and program, but I must not be good at this because I couldn't figure it out.

This happens when running Fiddler Everywhere for the first time, I've tried reinstalling it multiple times, running as Administrator and nothing.

 

I'm running on a Windows 11 pro, it's my personal computer there are no network blockers, I can ping the endpoints mentioned in this answer: https://www.telerik.com/forums/unable-to-accept-the-eula-please-try-again-later-if-the-problem-persists-please-contact-support

 

我一直在寻找Fiddler Everywhere 5.4.0版本中的自动回复功能，但一直没有找到。请问是取消了还是去哪里了？
