Fiddler doesn't work


Fiddler almost not work for me. Seems the problem only with https. For example to open https google.com I need to wait around 40 seconds

Screenshots:

immediately after request

after ~40 seconds

Fiddler log:

Many times in chrome I see: Waiting for proxy tunnel...and site shows This webpage is not available (ERR_TIMED_OUT)

In EDGE I even can't open http site for all sub requests I see blue up arrow which means fiddler trying to load it (after ~40 seconds I get loaded all that requests)

I tried to reset Internet Properties-> Advanced tab-> Restore advanced settings - it doesn't help me. Also I tried to restarted my system, also I restarted fiddler after any changes I made.

Fiddler settings: Certificates generated by CertEnroll engine. I tried to change it to MakeCert. Few times I reset All certificates, also manually removes certificates. Browsers: Chrome/Firefox

Gateway info in fiddler: No upstream gateway proxy is configured.

Recently I made clear installation of Windows 10. I do not have any Antivirus.

Windows 10 Pro x64 Fiddler v4.6.2.0

I need fiddler for my work. Please help me

UPDATED:

This is can be issue with Protocols. Currently in fiddler I have next protocols:

fiddler.network.https> HTTPS handshake to www.bing.com (for #4) failed. System.IO.IOException Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. < An existing connection was forcibly closed by the remote host 

and

fiddler.network.https> HTTPS handshake to www.google.com.ua (for #23) failed. System.ComponentModel.Win32Exception The client and server cannot communicate, because they do not possess a common algorithm

Solution

  • As I thought the issue was with protocols enabled in Internet Options in Windows and Fiddler protocols.

    I ticked Use SSL 3.0 and use TSL 1.0 in Interent properties (all other should be unticked) in Fiddler protocols I typed: ;ssl3;tls1.0

    And after this changes everything works perfectly
