I need to capture URLs for Oracle SmartView logins. I saw some video for fiddler classic to setup. but can you help me to do the same set up ln enterprise.

https://youtu.be/syUoIw8N2WQ

pls provide the steps for enterprise:

 

Whenever I try to open  3 Patti Lucky, the screen either freezes or stays completely blank for a long time. Sometimes it just loads halfway and suddenly disappears without showing anything. On other occasions, I notice the screen going black, and after a few seconds, it automatically closes without any message or warning. Even after trying multiple times, the same issue continues. I have restarted my device, made sure my internet is working fine, and even cleared stored data to see if something changes. I also made sure my device has enough storage and is updated, but the problem still doesn't go away. It feels like something is stopping the process from running fully, especially during the initial stage.

This issue started recently, and it wasn’t like this before. Everything used to work fine, and I used it daily without any problem. Now, it’s difficult to continue because nothing loads properly. I hope this problem gets fixed soon, or at least there is a proper solution or update available. If anyone else is facing the same thing or has found a way to fix it, please let me know.

Hello,

I have two questions regarding Fiddler Classic, and I would appreciate your help.

1) Cloudflare blocking error

When I try to load either of the two websites below through Fiddler Classic, I receive the following Cloudflare error message: "Sorry, you have been blocked." Please see the screen shot attached.

https://www.gurufocus.com
https://et3arraf.com

Both websites load fine when Fiddler is not active. Over time, I’ve encountered the same issue with several other sites as well — the two above are just recent examples. It seems this error has become more frequent lately.

Do you know why this happens? Is there any way to bypass or prevent this issue?

2) TLS 1.3 support in Fiddler Classic

Could you please provide an update regarding the implementation of TLS 1.3 in Fiddler Classic? Is it still under development, or has the upgrade been officially discontinued?

No recent news here: https://feedback.telerik.com/fiddler/1584209-support-tls-1-3-now-that-net-framework-does

Please note that I’d consider switching to Fiddler Everywhere, but I’m currently relying on a large script that only works with the Classic version, since scripting isn’t yet supported in Everywhere.

Thank you in advance!

Best regards,
Alex

When I try to analyse the requests on Yahoo Finance, I see different results when requesting from a browser with Fiddler turned on compared to the same request when Fiddler is turned off. I also tried different capture methods (System Proxy, Network Capture and Browser), but the same occurs. If I use this url:

 

https://query1.finance.yahoo.com/v8/finance/chart/IVV?events=capitalGain%7Cdiv%7Csplit&formatted=true&includeAdjustedClose=true&interval=1d&period1=0&period2=1747180800&symbol=IVV&userYfid=true&lang=en-US&region=US

 

Opening this url in a Chrome tab with Fiddler turned off, everything works fine (HTTP 200 response). Wih Fiddler turned on, however, the site responds with a HTTP 429 code (Too Many Requests).

 

Why this is happening?

HI All,

I get the following error when trying to open .saz files.  Do you know what is happening and if I get other .saz files recorded, is there a particular setting I should look for?

Following guide online to swap out the old max speed with the new max speed but i'm using a mac whereas most people used fiddler classic on windows and i'm not sure whether I put the values in the correct places within the rule.  Anyone spot my noob mistake ?  Seems like many people had success so I know it's possible and my phone with the app making the API calls is connected properly to Fiddler that's not the problem. Please any help is so appreciated ! Thanks so much

websocket message garbled

Hello, for some tests, I'd like to use Fiddler to route through the corporate proxy network and, in a specific case, process requests/responses directly with mitmproxy scripts (because Fiddler Everywhere doesn't yet offer the same functionality as FC).

So I connect Fiddler to mitmproxy by setting the gateway proxy to mitmproxy listening at localhost:9090.

But it seems that Fiddler doesn't respect this setting. It always routes through the internet normally.
Even if I intentionally configure the wrong proxy port, the connection persists.

What should I do? Maybe I got wrong something??

 

I'm using Fiddler in Linux and already added certificates of Fiddler and mitmproxy to the system (actually i'm using the same one).

I keep getting this warning and as soon I click, I get it back. I think one of the security apps is monitoring and locking down the proxy server setting in Windows. I am running Fiddler as an admin and manually setting the proxy server but my setting is instantly removed.
It seems I can't use network sniffers that depend on certain proxy server settings.

Does Fiddler Anywhere suffer from the same issue?

I am running
