You mean Chrome traffic doesn't show up in Fiddler? Or Chrome gets no traffic?

What versions of Chrome and Win 10 exhibit this problem? Do you know what version you upgraded Win 10 from?

I am having the same problem, any solution or workaround?
Chrome Version 64.0.3282.186
Windows 10 Enterprise, Version 1607, OS Build 14393.2007
Fiddler v5.0.20173.50948 for .NET 4.6.1

No problem with this setup:
Chrome 64.0.3282.186 64-bit
Windows 10 Pro 1709 16299.248, Updated several times.
Fiddler v5.0.20173.50948 for .NET 4.6.1
No special proxy settings.
Is your Chrome using IPv6, but IPv6 support is turned off within Fiddler?
After you start Fiddler, then start Chrome, what proxy settings does Chrome show? See my attached screenshot.

Glad to know that it works at your end. Things were working fine for chrome, until I got this new version updated.
I do have 'Enable IPv6' option turn on.
And my proxy settings is similar to yours, expect that I have port :8888 instead of :8899 (check screenshot).
Since I a have :8888 under Options>Connections>Fiddler listens on ports, I guess :8888 is okay.
I have also tried resetting fiddler's ssl certificates and re-installed chrome, and fiddler.
Does Chrome loads pages successfully? Is this the only program, whose traffic does not show up in Fiddler? Are there by any chance any Fiddler filters turned on?

Hi Alexander,
Yes baffling indeed, Chrome loads page/sites successfully. Actually I am posting this using Chrome, but I don't see any traffic capture by Fiddler. Fiddler works as it should for Edge and Firefox, no problem there.
And nope, I don't have any Fiddler filters turned on.
Initially I thought this problem was because of the `Strict site isolation` settings which I enable for Chrome. I have disabled it, and actually re-installed chrome without much luck.
Cheers
The problem can be caused by 2 main reasons - either Fiddler is not a proxy for Chrome's traffic or Fiddler hides Chrome's traffic. In order to check if it is the second option go to Help -> Troubleshoot and check if the sessions appear in the sessions list with strike-trough font. If yes, then the comment column in the session list will point to the reason to be hidden.

Hi Alexander,
Yes seems like Fiddler hides chrome's traffic. I see this as the comment in the strike-trough font line.
# Result Protocol Host URL Body Caching Content-Type Process Comments Custom
0 - ? 0 chrome:12000 Hidden due to stealth-NewOrReusedClosedWithoutRequest. Hidden due to stealth-NewOrReusedClosedWithoutRequest.
We getting somewhere, I did a quick google search on "Hidden stealth-NewOrReusedClosedWithoutRequest". One person was able to solve this by disabling chrome extension so I went ahead and disable all my chrome extensions and restarted chrome. But that didn't solve my problem. May be you have better idea on what does this mean, and how to resolve it ?
Are all of the hidden Chrome sessions with this message?

Hi,
Yes that's right, all the hidden Chrome session has this message.
Do you know what that means?
Cheers
Please, excuse me for the delay in my answer.
Sure. It means that Fiddler failed to read the request from Chrome. At first glance this seems to be very strange, since you can see Chrome loading pages. Have you enabled any experimental features of Chrome?

Hey
Yes I originally enabled `Strict site isolation` experimental feature but I disabled it and went as far as to reinstall chrome, nothing helped. Never the less, your explaining of reason behind the 'hidden due to stealth' error gives me some idea. This weekend I will install some process monitors and try to trace what's going on. Thanks for all the help, appreciate it.
Cheers
Okay. If you need any help, please, do not hesitate to contact us again.
