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.

Just downloaded and tried to use Fiddler Everywhere for Mac osx - 

MacBook Pro (15-inch, 2017)

16 GB 2133 MHz LPDDR3

Catalina - 10.15.7 (19H1922)

 

When I launch Fiddler Everywhere 3.3.1

Nothing happens it tries to start, says loading in the prompt then crashes.

I am trying to do the trial

 

Any advice?

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.

Hi guys,

I'm using different proxies for each browser, let's say 5 different proxies/IPs.

The question is: How to make the fiddler classic capture the traffic (requests/responses) from all the browsers? It means that it should read the traffic from 5 proxies at the same time.

Having updated Windows 10 to 11, fiddler will no longer launch. 

I've tried uninstalling/reinstalling, but see the same effect.

The application event log shows the following pair of entries each time:
