I found when some app use this type post, fiddler can not get the response.

[Fiddler] The connection to '::ffff:220.233.36.113' failed. <br />Error: AddressNotAvailable (0x2741). <br />System.Net.Sockets.SocketException The requested address is not valid in its context [::ffff:220.233.36.113]:80

Hi,

 

I set Fiddler as a proxy per this official link , but when I ran my NET Core app in Visual Studio and Firefox I noticed that no requests between FF and my app were displayed in Fiddler. At the same time, all requests from Firefox to the Internet were shown excellently. All applications (Visual Studio, Fiddler and Firefox) were run under administrative account on my machine. What should I do to have requests from FF to  my NET Core app shown in Fiddler?

OS: Win 10 x64 Pro 21H2 (19044.1526)

Firefox: 103.0.2 (64-bit)

Fiddler: v5.0.20211.51073 for .NET 4.6.1 Built: Wednesday, December 15, 2021 64-bit AMD64, VM: 75.0mb, WS: 125.0mb .NET 4.8 WinNT 10.0.19044.0

Visual Studio: Microsoft Visual Studio Community 2022 (64-bit) - Version 17.3.0

Previously I could not play games without Fiddler classic open,  hoping my computer would go back to how it was before I installed fiddler, but now I can't play games at all. How can I play games without fiddler, or how can I restore my computer to what it was before without erasing my files or something?

In Fiddler Classic decryption I set <client> and tls 1.2, I'm capturing traffic from mobile application via Fiddler proxy working in local network on Win 10 machine,

but still B2C in Safari shows me message "This Connection Is Not Private", and says it shows this because site uses tls 1.0 and tls 1.1;

is it solvable?

In the beginning I had only tokens: <client>; ssl3; tls1.0; tls1.1 - but then I added 1.2, should have I reissue certificates ?? (suppose that not)

What can be the issue?

Thank you much.

I have tried to uninstall, reinstall, but nothing worked.

If i tried to login with my telerik account, it gives :

If I tried to create an account, I don't get the verification email.

Not sure what I missed.

 

Sincerely,

When I run fiddler with a proxy for the BlueStacks Android emulator (on Windows), many of the results are listed as "Tunnel to" a random IP address, with no headers and no information on the data sent. Clicking on one reveals "A SSLv3-compatible ClientHello handshake was found. Fiddler extracted the parameters below." but nothing else that I can decipher.

I have HTTPS capture and decrypt on, and it works for a few API calls from this app, but the majority are shown as the IP addresses explained above.

Am I doing something wrong? How can I fix it so that I can see information on these.
